System Boiler Advice

4 years ago

Hello,

Building work on our 1933 detached house is not due to start until next year at the earliest (we are literally at the beginning of the process, architect came around last month to complete the measured survey).

However, the current boiler is 32 years old and as you can imagine, not very efficient. We moved into the property in March, so we have not had the pleasure of living with it through a Winter. It is presumed the gravity-fed cylinder and headed tank arrangement are also of a similar age.

Preferably, we would like to keep warm in the coming Winter which means installing a new boiler/cylinder prior to the rest of the heating system being updated.

After a little research, I feel a system boiler setup would work best. We have installed PV panels and any excess currently goes through an 'iBoost' to the immersion heater reducing our gas bill a little.

In terms of the refurbishment work, we do not have any final plans, just ideas.

Ideally, the brief is to have a 4 bedroom property that includes a loft conversion with en-suite, a main bathroom and underfloor heating to the ground floor with downstairs WC and utility (not asking for much, right!?).

At the end of the day, a new boiler/cylinder can be moved as and when we know where it needs to go. My question is, what size boiler would you recommend (kW) to ensure it's future proof?

Help appreciated,

Matt

I think Matt this kind of advice is perhaps beyond the remit of most of the Houzz community. I think you need a Gas Safe engineer to advise you. My old boiler was of a similar age and was fantastic, heated the home beautifully. We only had a new one installed because my husband was retired and qualified for a new one at the time.

You can do an online calculation to work out how powerful the radiators need to be to heat each room and then total how much power your boiler needs to deliver to those radiators.

Downstairs loo/boiler problem!

I was thinking that if you boxed the whole wall out to the window but then boxed around the boiler separately (so the boiler front stuck out) then either side you could add little shelves to balance out the centre and to put plants on against the tropical wall paper you want. That’s if you don’t want to lose some window. I would also paper the front of the boiler access door to blend it in. If you aren’t losing too much of the window then I would box across and make the window rebate smaller to account for it. But more work but it depends on what you can live with

Will combi boiler be OK?
Q
Comments (6)
We also have two bathrooms and WC with combi. We cope fine but one shower is electric and never, so far, found ourselves wanting to run two showers or bath and shower at same time. It would struggle too much. Also remember that combis are either heating water or radiators, so take a shower and heating cuts off. And as you don't have a pressurised water store with a combi you are dependent on the incoming water mains flow rate being enough to serve multiple outlets (and a boiler model that can keep up). they also need more volume of gas, so not uncommon to have to upsize incoming gas pipe (ours was ok for 30kw model, any higher and I think it would have been a problem). There are large storage combis, such as Worcester highflow, which claim to cope, but that's when gas pipe size is likely to be a problem. They are great spacesavers, and can't run out of hot stored water, but need to be aware of their limitations.

Basement boiler room too BIG!?
Q
Comments (2)
It is not the only route. An alternative route is via the ground floor main door, but has to make a big detour around the house and down a flight of stairs. My initial thought was also to turn it into a basement reception room instead. Indeed... hence I'm quite hesitant to build a separate utility room next to the kitchen. But if the majority thinks it's wise, I'll have to make a rethink about it (as the current kitchen space is quite spacious as well, just the layout I need to rework) Also I have a hunch that a toilet/shower room might come in handy for this basement, so that anyone in the basement need not walk up and down the stairway whenever they need to use the washroom. But not sure if to stay with a simple toilet OR to add a shower room in there as well (OR to include dryer/washer instead).

Back Boiler - what's the procedure?
Q
Comments (4)
A decent Gas Safe plumber should be able to remove the back boiler, cap it off and then install a new one in the garage if you have one, or in the utility room or kitchen. If the new boiler goes in the kitchen then a cupboard could be fitted around it to keep it tidy. The fireplace is a bit naff (sorry) so you could remove it and depending on your style you could add a new one with an electric fire. There are some lovely modern ones now, or you could fit a log burner if there is a proper chimney.
