Types of boilers – which boiler is best for your home

Combination boilers (Combi)

Combination boilers (or combi boilers as they are more commonly called) are the most common boiler in the UK.  They provide the convenience of instant hot water on demand and heating with no need for water tanks or cylindersat any time.


  • you get unlimited heat and hot water when you need it
  • there’s no need for a cylinder in your aring cupboard
  • there’s no need for a tank in you loft
  • they don’t take up much space


  • the water pressure might be reduced if you need hot water from more that one tap at a time

Heat only (Conventional) boilers

Heat only or conventional boilers also known as open vented or regular boilers – have both a cylinder and a tank.  Hot water stored via a cylinder normally housed in an airing cupboard or boiler room and tanks located in the loft, heating is supplied pumped frm the boiler via a circulating pump and valves normally in your aring cupboard.


  • you get hot water from multiple taps at the same time
  • you can have backup hot water from an electric immersion heater


  • the hot water can run out and you’ll have to wait for it to reheat
  • you need to find room for the cylinder and tank

System boilers

System boilers also known as sealed system, just like a regular (conventional) boiler works on the principle of using a storage hot water cyilnder but no tanks in the loft as the heating and hot water systems are pressurised. Installation is quicker, neater, easier and more efficient. Faster heat output response and more economical running costs.


  • there’s no need for a tank in your loft
  • you can get hot water from multiple taps at the same time
  • you can have backup hot water from an electric immersion heater


  • the hot water can run out and you’ll have to wait for it to reheat
  • you need to find room for the cylinder somewhere

Condensing boilers

Condensing boilers arn’t strictly a boiler type – instead it’s an attribute your boiler can have, e.g. you can have a condensing combi boiler or condensing conventional boiler.

Condensing boilers are very energy efficient because they capture some of the heat which would escape from the flue of a non-condensing boiler and re-use it.  This means they get more heatfro mthe same amount of fuel, which will save you money on your heating bills.

All new boilers have had to be condensing since 2005.

What our customers say

Chris and his team were recommended to fit a new kitchen for me. They took care of everything, removal, fitting new kitchen, plastering and decorating. This team could not do enough for me and were key in helping me achieve the kitchen of my dreams. I cannot recommend them enough. Thank you Chris for understanding how much this meant to me and for making it stress free.

Sharon Richards, Bedwas

What our customers say

Highly recommend Chris and Mike, they designed and fitted a bespoke Bathroom for myself and I couldn’t be happier with the end result. Very professional and clean, they laid film down on the carpets before they started work and always tidied up after themselves. Would definitely use again and would recommend them to friends and family.

Paul Barnes, Caerphilly

What our customers say

I would highly recommend Chris and his team. They are very professional and nothing is too much trouble. They fitted a new downstairs toilet and checked with me at every stage about fixtures and fittings and it was completed to a very high standard. I would highly recommend them. Thank you, a very happy customer!

Suzanne Whiting, Bedwas

What our customers say

A big thank you to Chris and the Truscon team. They transformed our 1970’s small toilet room and separate bathroom into a seemingly more spacious modern bathroom.Their works included building works, plastering walls and ceilings, tiling, plumbing and electrics all done in a highly professional manner. The works were started and completed at the agreed times and dates. We are very pleased with the results!

John, Hendredenny

Chris and the team fitted my new heating system. Excellent job, very professional, clean and tidy and health and safety compliant with the COVID restrictions. If you are looking for work to be done on your property you will not find a better company that this. Highly recommend.

Chris gives value for money on the services his team offer. What makes TPS stand out is attention to detail. I’d recommend Truscon Property Services for any level of building work

Darren Barry

What our customers say

They came recommended and didn’t disappoint! Had a new Worcester boiler, pipe work and new radiator and even put a cupboard up! Arrived on time, left no mess and did a great job. Will be passing on the recommendation and wouldn’t hesitate to use again, thanks both!

Colette Lewis, Trethomas

What our customers say

Truscon have already been working with us for the last almost 2 years on a huge renovation so had no hesitation in asking him to do a smaller job on a property in Cardiff. Another great job thanks Chris & Mike!
