Buying guide, Boilers:

There are three main boiler types:

1.    Combi boilers

2.    System boilers

3.    Regular boilers

Understanding each boiler type is important to identify the one suitable for your house. The prices listed do not include the installation fare.

Combi Boilers:

Combi boilers or combination boilers do not need a separate hot water cylinder, instead deliver water from one solid unit. They are easy to install and cheaper than the other models and therefore popular among customers. It is best suited for smaller house with a wide range of kW outputs. The disadvantage includes the impossibility of the boiler to cope up with two showers or baths running simultaneously, not suitable for houses with many bathrooms.

The advantages of combi boilers include:

•      Prompt and limitless hot water

•      Energy efficient

•      No cylinder or tanks essential

•      Easier to install

System Boilers:

System boilers are ideal for houses with multiple bathrooms and great demand. They can provide a constant supply of water to all the units within a house. It requires a separate water cylinder for the storage of hot water, but they don’t need extra tanks. Like combi boilers, system boilers are easy to install energy efficient to run.

The advantages of system boilers include:

•      Provides hot water to multiple taps ideal for large house

•      Installation quick and easy

•      No need for separate tanks

•      Solar thermal solutions

Regular Boilers:

Areas with low water pressure and homes with multiple bathrooms are ideal for regular boilers, also known as conventional or heat only boilers. They are best suited for homes with loft space and airing cupboard as they need a feed, expansion tank and hot water cylinder. They provide a steady supply of hot water.

The advantages of regular boilers include:

•      Perfect for larger houses with two or more bathrooms

•      Simultaneously, provides water to multiple taps

•      Suited for homes with a traditional central heating system

What do experts have to say?

It is significant to guarantee that a boiler’s Power Rating (or size) is just right;

•      An undersized boiler might work too hard, and an oversized boiler may work below capacity. Both circumstances can lead to more fuel being used than needed.

•      A heating engineer analyses the dimension of boiler needed based on; heat loss, the number of rooms (Bedrooms, bathrooms etc.), number of people in the property, number of radiators, showers, etc.

•      Smaller houses and flats, with up to 10 radiators, will need a 24-25kw boiler. A 28-30kw would be installed for a medium to large 3-4 bed house with up to 15 radiators, and a 33-35kw and a 40kw would be for a large house with up to 20 radiators.

•      In enormous properties spread over several floors over one boiler would be essential.

Boiler Manufacture

•      There are abundant boiler brands / manufacturers. Each one has an advertising strategy to trade their product. As a customer it’s hard to tell which is “the best” or the right one for you.

•      The hunt for “the best” is often problematic by heating engineers having a preferred boiler manufacturer that they like to install. They will each say that their proposal is better than the other’s.

•      The cynical might suggest Heating Engineers prefer one brand over another because that is where they can make the most mark.

•      Maybe one brand is less likely to become incorrect than another, one brand is easier to install than another, or that the engineer is just more familiar with a particular brand than another.

•      A Gas Safe engineer will install a gas boiler of any brand, but it’s worth paying attention to why they endorse one brand over another. Quite often it will be because they can offer an extended warranty on that boiler brand.

  1. How Do I Know if My Boiler Is Economical?

If you’re buying a new boiler, or just trying to decide if you need one, how efficient it is will be a big part of your decision.

To find boilers that are economical, look for their ENERGY STAR rating. A well rated boiler should run very efficiently, whereas a poorly rated model may be more cost effective to replace in the long run.

You should find that all modern boilers are more economical when compared to older models.

 2. How do I know if I’m getting a Good Deal on My Boiler?
