Whether your existing boiler is unreliable, costly to repair or simply due for an upgrade, our engineers can assess your requirements and explain the options clearly. We serve Chesterfield and surrounding communities from our Doncaster base.
Choosing the right boiler for your home
Different properties need different heating and hot water arrangements. We’ll discuss your household’s requirements before recommending a suitable option.
Combi boilers
A space-saving option for many homes, providing heating and hot water without a separate hot water cylinder.
System boilers
Often suitable for homes with greater hot water demand, working with a separate hot water cylinder.
Regular boilers
May be appropriate where an existing conventional heating system is being retained or upgraded.
Experienced engineers, straightforward recommendations
A boiler replacement should be based on your property’s heating requirements, not simply the model already fitted. We can discuss system suitability, efficiency, controls and the work involved before you decide.

Reviews
Our Happy Customers!
We rang Kassgas on Wednesday afternoon. By Thursday afternoon we had a new boiler. Billy fitted our boiler, he was extremely polite and tidy he even took his shoes off each time he came into the house. Not enough words to praise him enough, he took time to explain how to work the new boiler and controls to two pensioners.
Billy and Matt were about to leave when we mentioned that our stop tap was leaking, they stayed behind and fit a new one. It was heartwarming to meet two young men who didn’t want to rip us off.
We would and already have spread the word about this company.

Billy and Matt just installed a new boiler. They recommended Ideal with a 12 year warranty. They turned up on time within a week of providing a very good quote. they removed the old boiler, installed the new one, flushed the radiators, added inhibitor, installed new halo wireless thermostats and checked everything was working ok in the space of 5 hours. They removed all the rubbish and left a very tidy finish.
I would definitely recommend themWould definitely recommend Kassgas if you have any heating or boiler problems.
