Need to replace an old Worchester 2+ Heatslave floor combi boiler (apparently one of the first combi boilers).
The house is an ex guesthouse on 4 levels (basement to converted attic) that used to have hot water in most rooms, but we've removed most of it now since we plan to use it for residential use only (2 adults, three kids).
When done we'll have two full bathrooms, one each on the top two floors. One with a bath, sink and toilet the other with a shower, sink and toilet.
There's also a on-suite planned on the ground floor inc. bath, shower, toilet and two sinks and toilet/sink in the basement. Kitchen will be like most kitchens
There are the following radiators-
Attic (4 rooms inc. bathroom) - 5
First Floor (4 rooms inc. bathroom)- 5
Ground floor (4 rooms inc. on-suite + long passageway 2 rads)- 6
Basement (4 rooms inc. toilet)- 5
So 21 rads in total.
We'll be using the house as a family home, but I'd rather take into account possible future uses for the house (we'll probably move in 5 to 10 years, so could convert back to guesthouse or other similar use in the future, like to keep my options open).
We had a British Gas quote and I wasn't convinced by the boiler model suggested. It was there highest rated combi boiler, but he said it would struggle if we used two baths/showers at the same time. Also gave a ridiculously high quote for new radiator taps (£40 each!!) I almost laughed at him when he said it's a difficult job to add new radiator taps because they have to add the PVC tape!!
Take a guess what the whole quote was for new combi boiler and 40 radiator valves (with fitting).
We've lived with a combi boiler for 5 years that can barely handle one bath so would rather purchase a boiler that can cope with two baths at once than one that will struggle.
I think a new system boiler is the way to go, my understanding is they have a small additional tank of water so they can heat more water per unit time. If I understand it correctly they work on the same basis as a combi boiler, but with storage (built in?).
So with the above in mind is a system boiler the way to go, if so any recommendations?
My plan is to buy the boiler myself and get a Corgi registered installer to fit it.
The house is over 100 years old, poorly insulated, but we are replacing a lot of ceilings and in the process insulating between floors (mostly for sound proofing, but will help with heat retention). When complete all windows will be double glazed. Not sure yet if we'll insulate the cavity walls, though the basement will have around 50mm of fibreglass insulation between the main wall and the battened plasterboard so that should help with heat retention.
Thanks
David
