Fitting a new boiler in a different location

[sophiejazz]

We need to replace our floor standing boiler, located in a kitchen cupboard. I am considering having a combi put in the garage (primarily to get rid of the header tanks in the loft and the hot water tank in the airing cupboard).
I know that the manifold is under the kitchen floor, which is tiled. Will the gas fitter need access to this if we change the type and relocate the boiler?
Also as the current system is microbore (43 years old) is this suitable for a combi system on mains pressure?

Everything is "doable", it all depends on the amount of money, time and disruption, you are prepared to agree to!

Your best course of action, would be to use your social network to source 2 or 3 recommended installers, in your local area, to visit your home, discuss, assess and quote.

Your incoming cold main will need to be measured for flow and pressure to establish if a combi (or uv cylinder) is practical.

I personally don't like small/mini/micro-bore, but it's a lot of work to replace it. It'll need to be clean as a whistle and after 43 years, will be a nightmare to flush, if it's in poor condition.

If you are unable to source good installers through friends and family then try something like mumsnet or local plumbers trade counter for recommendations and get and contact references.

Remember that a combi heats the water as required each time you draw water there is a lag of maybe 10-15 seconds whilst the boiler heats up if you add this to a long run of pipe you will wait ages for a drop of water from the garage to wash your hands or the odd cup, often you end up washing in cold then leave the whole run of pipe full of hot water that just cools down again.
The ideal position for a combi is in the kitchen as near as practical to the sink.

Are you sure your home is suitable for a combi boiler? Is your incoming mains pressure and flow rate sufficient? Are you happy with only really being able to operate one hot water outlet at a time?

43-year-old microbore might not be in great condition, but there are options there. For example, an Intergas combi boiler will run quite happily with a heating system pressure of 0.5 bar (even down to 0.1 bar if required, but 0.5's probably about what your current system pressure is) so if you did go down the combi route running the system at a lower pressure would be an option for you

Plate separation too might be a wise option.

I agree with muggles. An old system like that could be big trouble & very dirty. The Intergas boiler is a good call & as said, get 2-3 quotes from recommended local guys.

Many thanks, I'll discuss this with the gas fitter. One local company we had out only fits Worcester.

There is a world out there that coexists alongside WB boilers

There are a lot of options, but these have to be thought through
Fitted a Baxi condensing combi with a plate heat exchanger between boiler and existing micro bore system not much younger than your system

Three years on, it has not missed a beat. Any brand of boiler will run that way

Intergas will take place of you existing boiler but keep it open vented (small cistern in the lost)
