Re: Change to combi-boiler?
We had a Glow Worm condensing boiler fitted around five years ago, which cut our gas usage by around 30%. It is serviced every year on a contract which then guarantees the whole central heating/water system for the next twelve months. The only problem that we've ever had was last December when the small outlet pipe froze outside. We live in a hard water area but I haven't been told that it's a problem, but with the system being under contract it shouldn't be my problem!Re: Change to combi-boiler?
Re: Change to combi-boiler?
You are right, we did not have our first boiler adequately insured. When the second was fitted, they did something called a 'flush' with some sort of chemical, this took a couple of hours or more. Apparently they could tell this was not done on the sysstem when the first was installed. We are well covered now for any eventualities.Re: Change to combi-boiler?
I agree with John, it is essentail to take out breakdown insurance with modern boilers.Re: Change to combi-boiler?
Don't get a combi boiler if the house has microbore pipes get a condensing boiler instead.Re: Change to combi-boiler?

It maybe worth mentioning.Re: Change to combi-boiler?
I ripped out the immersion heater and tank circa 10 years ago and installed a Mistral combi-boiler. The tank in the garden was the only real difficult thing to get correctly placed. It was arguably one of the best moves I've made. This was a disregarded old property that hadn't been occupied for 9 years,at the time. I put in 8 radiators around the place [it's an old bungalow] and was able to get all kitchen plumbing onto one wall. The radiators work off a thermostat set in the main room-but they can be turned off during warm months,so just the hot water is being supplied. As stated above,the hot water is constant-if a tap/the shower is on,then the water is hot for as long as it's required. Servicing is just a case of changing filters and checking for scale...which we don't have much trouble with out here as it's soft water. I'd recommend combi-boilers over electric or gas central heating and hot water supply every time.Re: Change to combi-boiler?
A combi set up does not store hot water, which on one hand is quite efficient, but wastes a lot of water as the burner kicks in, I.E, if you just want to do some washing up, you need to run the hot tap for the equivalent of a bowl full of water just to get it running hot, could be a problem if on a water meter.
