Choosing the right boiler for your home can be difficult. Hence, a proper understanding of your home’s requirements and the options available in the market is important to making the right decision.

A boiler is likely to be one of the costliest household purchases you’ll make. Therefore, choosing the best new boiler for your home at the right price is very important.

So, here’s given a boiler checklist for your convenience.

Boiler Checklist

Before reaching to any decision, you need to decide which type of new boiler to go for. As such, here’s what you should consider.

Fuel Type

Most UK households have a gas heating system equipped with a gas boiler. But if you’re one of the estimated 4.3m households not connected to the UK’s gas network, there are alternatives. These include fitting an oil boiler, LPG boiler, high efficiency storage heaters or perhaps even a biomass boiler, ground or air source heat pump.

Boiler Type

If you have a gas heating system with a gas boiler, you need to choose between:

1) Combi Boilers

Also known as the combinational boilers, these are the most popular kind in the UK. These provide heat and hot water without the need ofwater tanks or cylinders. You can opt foreither an electric or a gascombi boiler. 

These are very popular in flats and smaller properties, though they are becoming more popular in larger houses as now there are more powerful options to cope with the extra radiators and showers.

Combi installations will typically be cheaper because almost everything is contained in the boiler which negates the requirement for disturbing other areas of the house.

One of the potential downsides of combi boilers is that there is no store of hot water, as it is produced on demand. This may not suit all households if there are multiple people wanting to take a shower in the morning in multiple different bathrooms! The combi will work in terms of priority of where heating is required in the system, so you may get some shrieks from the someone under the shower upstairs if someone starts running a bath downstairs! Larger demands for hot water at any given time can often be better suited to systems boilers.

2) System Boilers

Also known as sealed system, these come with a water cylinder and no water tank. The greatest benefit of this type of heating system is having the ability to draw hot water from multiple taps at any given time. This is because a buffer of hot water is stored in the tank.

The tank does not require a cold water feed which can save space in the loft though of course you will need somewhere to put a large tank. The cost of the this will typically be larger than that of a combi installation as there are more component parts to the system, the material cost will be greater and the disruption from installation may put others off.

For people in larger homes though this is often a very good option.

3)  Conventional Boilers

Regular boilers or open vent, as they’re alternatively called, conventional boiler have both a cylinder and a tank. These are suitable for homes that need to have hot water in more than one room at the same time.

4) Condensing Boilers

Condensing boilers aren’t actually a boiler type –rather it’s an attribute a boiler can have. These boilers are very energy efficient as they capture heat preventing it to escape from the flue of a non-condensing boiler and re-use it. This means they receive more heat from same amount of fuel, helping you save money on your heating bills.As of 2005 all new build constructions with gas boilers installed in Scotland must be condensing boilers.

5)  Energy-Efficient Boilers

All new boilers these days are energy-efficient. Boilers must be A-rated for energy efficiency (at least 88% efficient) since 2010 according to the government policies in the UK.The energy efficiency rating system for boilers is called SEDBUK (Seasonal Efficiency of Domestic Boilers in the UK) now being updated to the ErP mechanism. Boilers of every kind are assessed and given a rating accordingly to help you pick a boiler, which is energy-efficient.

Boiler Efficiency

Boiler efficiency is an integral part of determining boiler reviews. According to the Energy Saving Trust, if you have a gas central heating, your boiler will account for about 60% of your home’s CO2 productions. This makes your selection of boiler a key priority if you want to cut yourcarbon footprint and energy bills. With boiler efficiency ratings, you can filter your boiler reviews.

Heating Controls

Heating controls is a good way of handling your heating costs as it allows you to ensure that your heating is on certain rooms at certain times. It may be a good time to install a heating control system when you come to replace your boiler.

So Where do I Stand?

Have a look to see where your boiler can be placed. Ideally for most boiler this will be in a place on an outside wall to allow the flue direct exit from the property.

Often boilers are placed in the kitchen as this gives easy access to all plumbing elements in the property.

Moving it away from these elements will generally incur more costs due to the more complex install and more materials required.

When you’re looking at the price, and everybody does, consider what you are paying for: How long is the warranty? What is the power of the boiler? Has the boiler got a good reputation?

Besides these considerations, consulting a professional is always a smart move!

    The boiler in our house needs to be replaced and I’m trying to find which would be the best boiler to get. I had no idea that there were so many different types of boilers. I think a conventional boiler would probably be the best to get, now I just have to find someone to come and install it in our house after we buy on.

  2. Marie Watson says:

    Conor, thanks for putting some tips together for choosing a boiler. I didn’t realize that there are so many options when it comes to choosing the type of fuel and the type of boiler you need. You make a good point about how important it also is to make sure your boiler is energy efficient. I would think that it is important to make sure the one you choose is efficient enough to handle your home or building.
