Combi, Electric and System Boilers Compared 

Replacing a boiler is one of the biggest home-related investments a Bristol homeowner may have to make. It is not just about the cost of the new system; the decision you make can determine how reliably your family gets heating and hot water for many years to come. For homeowners considering a new boiler Bristol, taking time to understand the available options can help you make a more confident decision. 

A new boiler will, however be much more energy efficient than it’s predecessor and thus can save money in the long run, but the efficiency of the boiler used, depends greatly upon the size of the property in question, the number of rooms heated at any given time as well as the demands placed on hot water by, say a large family.

Bristol homes can vary enormously, from small modern apartments in the city center to sprawling traditional family houses in the suburbs, there simply isn’t one standard solution that applies to each. This guide will endeavor to clarify what are the main indicators that a boiler has failed, the options available for new models, the calculations needed to achieve the correct boiler size, what a typical installation requires and also what a Bristol homeowner needs to consider when selecting an appropriate boiler installer. This guide also touches on post-installation paperwork and possible financial help available. Although often planned to a certain degree the process still remains the greatest stress of a boiler system upgrade, therefore with adequate knowledge of what the process entails it will be able to be far more easily controlled.

Signs It Is Time for a New Boiler

Boiler at the end of its useful life and will typically make itself felt in the short while before complete breakdown. More frequent call outs, an escalating repair cost, and problems sourcing individual components can all be symptoms of a unit that is time for replacement, rather than further repairs. Most boilers are designed to last up to 10 or 15 years, at which point their efficiency will typically begin to decline even when they are otherwise still operational.

Some of the symptoms that may become apparent are rooms taking longer to warm, and hot water running out sooner than before, suggesting the system just can’t cope with the demands.

Some older systems also develop a distinct clanking or whistling noise over time that they didn’t have when originally installed, in particular when working harder. If the engineer performing the boiler service stated that it was time it was replaced, or the last few repairs you carried out now total an equivalent cost to fitting a brand new one, the installation of a new boiler will undoubtedly be a better choice.

Choosing the Right Type of Boiler for Your Home

You’ll find three main kinds of boilers are used in UK homes and each sort comes with its own pros and cons: – A combi boiler. This type heats water on demand from your mains water system meaning there’s no need for an independent storage tank.

Which makes them ideal in a smaller flat or modern apartment where there may be limited space. – A system boiler.

This system boiler will also need some additional pipework to include space for a hot water storage tank in your house, although you won’t need to put a tank in the loft. This choice works with houses which have more than one bathroom. – A regular boiler. This conventional style of boiler has a similar set up to the system boiler as both types utilize both a cylinder and a loft tank. You will likely to purchase a system to replacement an existing one like this, to sidestep extra pipework work required to set up.

This boiler will be the right one for you if you need multiple baths and you need more than one person utilising these around the same time, or if the property design necessitates a particular boiler configuration or layout.

In addition to conventional gas powered models, it is increasingly likely that you could be fitting out smaller Bristol homes, notably flats where there is no gas supply, with electric boilers. Electric boilers are quieter and take up much less space. Their running costs are higher than gas.

System boiler they are one of the biggest options in the UK household of several people that often run the shower, taps etc.

In order that water goes everywhere with no drop in pressure. One can say that one has the option of most cheaper models of installation since they do not need boiler storage tanks, although with two and more people wanting hot water one in each place may be problematic. In other words one should choose it by way of actual daily living habits and not at a cheap price.

Sizing a Boiler for Your Bristol Property

Boiler output, measured in kilowatts (kW), is another important factor to get right when choosing a replacement. A boiler that is too small may struggle to provide enough heat for the property, causing it to run for longer periods and potentially increasing wear over time. On the other hand, a boiler that is too large can cycle on and off more frequently, which may waste energy and place unnecessary strain on the system. For homeowners considering a new boiler Bristol, choosing the right output is an important part of getting the best performance from a new heating system.

An old terraced property such as in Bristol would have solid walls and less insulation and would require a marginally larger boiler than an equivalent size new house with appropriate insulation: the difference is great enough to effect which boiler is required.

Extension of the house, the creation of loft spaces or the addition of more radiators will, of course, result in a change in required size, so calculation on the current state of the house would be more appropriate than the sizing calculation of a predecessor. A surveyor should calculate this; estimations would simply not suffice as the impact of receiving an incorrect size will continue to effect your bills for many years into the future.

The Cost of a New Boiler in Bristol

The price of a new combi boiler is influenced by many factors. The type and brand of boiler chosen plus any additional work required to fit will increase the price you pay. A basic like-for-like combi boiler replacement, where the new unit takes the place of the old one is typically cheaper as no additional pipe-work is required.

Installation of the boiler in a different place or changing from a conventional boiler system to a combi unit, or adding a filter and new control to the system will add to the overall price of the boiler.

Many customers decide to have a magnetic filter and a new modern type smart thermostat also fitted at the same time as replacing the boiler, this just adds a small amount to the upfront cost but could save faults and efficiency in the long run. Labour prices in Bristol are similar to the South West on average but it is certainly worth receiving a couple of detailed quotations before accepting the initial cost presented as prices will vary from installer to installer. Work undertaken for a particular price should always be broken down as to exactly what that cost includes – the price of the actual boiler itself, any additional components required and the price of labour.

What Happens on Installation Day

An easy combi boiler replacement will typically be completed in a working day, but switching from an old-fashioned system to a combi, or moving to a property requiring new pipework, might take a couple of days. Your engineer will remove your existing boiler after draining down the system before they attach a new unit and connect this to the gas, water and electricity supply. They’ll then fill the system up, check for pressure and leaks and fire it up on the correct setting for your home.

It is good practice to also bleed your central heating system, or as a good add-on to the install as if any debris from the old system is still present in the pipe work, it will potentially reduce the life of your new boiler.

It makes sense to make arrangements for you to be at home all day as the engineer will need access to your rooms in order to bleed your radiators and make sure all areas of your home are receiving adequate heating. The engineer should advise you on how to use the new system, once they’ve fitted it and can answer any questions you have.

Permits Building Regulations and Certification

Fitting a new boiler in England requires notification under building regulations, and in most cases your Gas Safe registered installer will let the appropriate body know on your behalf once the installation is completed, so you do not have to apply for this yourself. After the work is complete, your installer should issue a Building Regulations compliance certificate, plus a benchmark or commissioning certificate for the new boiler (this can be required to ensure your manufacturer’s warranty remains valid), and you should store both documents in a safe place ready for if you ever have to make a claim or plan to move house. Certain situations like the location of your boiler changing or alteration to the flue path may require further certification which would be wise to confirm with your installer at the quotation stage.

Government Schemes and Financial Support

You may qualify for help with installing a new boiler, or potentially other heating upgrades, such as Grants which are sometimes available which can be used against the price of a heat pump instead of a boiler.

Schemes can range, from a system based on your income, the EPC rating of your house, type of heating installed and other, the parameters do change from year to year.

Always refer to up to date criteria for which grants apply as even the terminology can alter, and not everyone is eligible for the same schemes in the same way. Local Bristol engineers may know which grants are operating right now and what your household is likely to be eligible for at the point you contact us. Always double check the scheme provider details.

Choosing an Installer in Bristol

Just as with boiler servicing, any installer working on a gas boiler must carry a Gas Safe registration; an obvious thing to verify before you commit to a quote. And aside from simply being qualified by law, you will also want to inquire as to just how long a company has been trading within the area; what guarantees and warranties are given on the actual boiler, and indeed the work they provide; whether they are an approved installer for the make of boiler you plan to install (which could allow you to have your warranty extended by the manufacturer. Viewing comments left by customers in Bristol; obtaining a reference or two from past works; is all rather more informative than is the cost alone.

You’d also be prudent to understand who is responsible for decommissioning the redundant equipment; be it an old gas boiler itself; and to ensure that is reflected in their quotation for work.

Good installers; or at least professional ones – will complete a site survey prior to offering costs and be prepared to clearly articulate the rationale for the boiler that their recommendation is based; to clearly list the entire scope of the work they have agreed to perform; rather than rely solely on an ‘handshake’ agreement.

Getting the Most from Your New Boiler

Once your new boiler is up and running, a few easy steps should ensure your investment stays on track, with no unwanted surprises on future bills. Registering the new boiler manufacturer is another key point of reference – usually within 30 days of installation, as this typically activates the manufacturer’s full warranty period. Scheduling an annual service at approximately 12-months following your installation ensures that your manufacturer warranty will continue, and allows a qualified Gas Safe engineer to make initial checks on your new system to make sure all aspects are still functioning adequately.

Using your heating controls wisely rather than solely relying on pre-sets can make a surprising impact in both comfort and energy consumption.

Your installer will no doubt be able to spend a bit of time explaining optimal settings of your controls when they come to leave and leave your installation. Keeping the workspace clear and promptly responding to any knocks, bangs or odd hums, will result in years of reliable heating and hot water from your new boiler.
