2 boilers?!

[briSk]

Right take the piss if you like but i have had a thought!

My house is actually a bungalow. and more than that it's a really long bungalow which hopefully we'll make longer by adding a bit on to.

so what i have thought is - is there any benefit to having two boilers? one for the front end and one for the back end? you could then effectively 'phase' the heating. you could have one for the living half dealing with it's heating and hot water and one for the sleeping part.

or does it always make sense to just get a single dear boiler with some sort of pump? i am just wondering about losses in always pumping hot water to the extremities of the house..?

any thoughts?

also can someone help me out on switching from radiator to underfloor heating. we have some suspended floors and some (minority) concrete scree type. as we go through the house renovating it i was wondering if we could convert each room to underfloor heating on the same 'circuit' as the normqal heating. then when the russians bend us over for the gas in 2021 i can dig up the garden and swap the boiler for a gournd source heat pump...

I wouldn't have thought that lagged pipe loses much heat - and any heat that does escape will save the boiler from having to heat the rooms

Given that a second boiler will cost around £1,000 to buy and fit, how long will it take for the heat loss from a lagged pipe to cost £1,000? Several centuries I suspect!

ETA I suppose that one advantage of having two boilers is that when one goes bang, you have a ready supply of spare parts!

We have fitted two boilers as opposed to one in big houses. You tend to have a primary one which will be on more often. The second boiler will come on to back up the primary. These can have their roles swapped every service (yearly) to give equal load throughout their life.


For example.

One smaller boiler would probably cope with the hot water in your house during the summer, when you won't have much heating on. Advantage being that you don't have to run a big boiler for most of the year - lower running costs.

Then come the winter, the second boiler would come on more often to keep up with the demand for hot water and heating.


You do on the other hand, have two boilers two go wrong, two to buy and install and two to service.

sounds very like mine, we have one boiler but have 2 heating zones, 1 for each end, and of course a seperate zone for water, so we have two drayton programable room stats 1 for each end.

before i did this i was thinking about having 2 boilers
