The essentials for the perfect boiler.

A boiler has two main roles: to heat the air inside a house and to also heat the house’s water. It does this by burning a fuel -oil or gas and makes very hot water. Some of this water feeds the plumbing system when the faucet is turned on. But it also pours through an organisation of closed pipes and radiators throughout the house, transferring the warmth to the air. As the water cools down, it is pumped back into the boiler to undergo the same process again. Glow-Worm Easicom Combi Boilers comes in two different output options 24kW and 28kW. Your Gas Safe boiler engineer would decide on which output you would need to run your home effectively and comfortably.

Check out these 2 best boiler options that would help you to have a perfect bath.

Buying guide, Boilers:

There are three main boiler types:

  1. Combi boilers
  2. System boilers
  3. Regular boilers

Understanding each boiler type in detail 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 delivers 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 are able to 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 and economical to run

The advantages of system boilers include:

  • Provides hot water to multiple taps at the same time, ideal for a 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, traditional, 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
  • Well-suited with solar thermal solutions

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 large properties spread over several floors more than 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 that Heating Engineers prefer one brand over another because that is where they can make the most mark.
  • It might be that 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 be able to 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 particular boiler brand.

Stories from the real world usage:

Reviewer: Ian M

Rating: 4/5

Date and Place of review: the United Kingdom on November 16, 2020

Feedback: We had a slight leak from one component in the boiler. The engineer came, confirmed the faulty part and ordered a replacement. As soon as the replacement was available the engineer returned and fitted the part explaining exactly what he needed to do and why.
Throughout the process the level of communication was very good and we were not left wondering what was happening. Even when the part was delayed the engineer contacted us to explain the delay.
Very good all round service.


  1. How Often Should I Replace My Boiler?

The general lifespan of a boiler is around 10 to 15 years. While this is an average, your boiler may last longer if proper maintenance is given. Considering a new boiler when repairs becomes too expensive would help save money in the long run. An expert engineer would help you decide the right time to replace your boiler.

  •  How Do I Know if My Boiler Needs Repairing or Replacing?

If you have a boiler fault it’s most likely a common problem with a simple fix. However it can be problematic to understand whether your boiler can be repaired or not when a more serious issue arises.

  • How Often Should I Get My Boiler Serviced?

Servicing your boiler once a year should help to prolong its lifetime. Even though servicing without an visible issues seems unnecessary, it would help to find the hidden faults.


Glow Worm Easicom System Boilers score high in terms of build in quality and consistency. The only difference in the models shown of Glow-worm boilers is their output and flow rate.  It is best to do some personal research to double-check what others are saying about the brand and model.
