No idea with what type of system i will require for a 6 bedroom/bathroom house

[Amar]

Thanks for everyone's input. Really appreciate it!

On another note (I'm going to hijack my own thread)

I am in the middle of purchasing another property up north. It's based over 3 floors plus a large cellar. Currently a 7 bedroom and looking to convert it into a 10 bedroom, 10 bathroom house.

It is so old it doesn't even have any central heating or a boiler. It still has the old slave quarters above the kitchen at the back of the house. (it really is a blast from the past)

Again I will be looking to get some local heating engineers out to quote me (anyone from stoke fancy it) once planning has gone through but in the meantime I again am trying to get my head around what can be possible.

So my idea was to have a boiler purely for the hot water by an unvented system, I guessing 3x 300l tanks? overkill?? situated in the cellar. Would it have enough pumping power to send the water up 2 floors to 3 bathrooms on the top floor, 5x bathrooms on the 1st floor and 2 bathrooms ground floor. All mixer showers but I will be fitting some sort of eco friendly shower heads and taps also to help save with water usage.

And then have a separate boiler just for the central heating. 10x towel radiators and 15x 1000x700 double radiators.

imguessing this wont be an economical as having it all fed off 1 single boiler but are there other options?? commercial sized boiler as chuck mentioned?

Has anyone ever used electrical radiators in bedrooms instead??

If you go for a fast recovery cylinder, something like a Joule Cyclone High Gain for example, and match it to an appropriate boiler on a hot water priority setup, you can get away with a much smaller cylinder. A 300L Cyclone HG will heat up from cold in just 17 minutes, and if the boiler is firing while the showers are on I think your biggest issue would be whether the mains can keep up rather than whether the cylinder is big enough. They also do a 400 and 500L version

Hi, with the development of a property for letting its commercial.
The rent pays back the investment etc.
I would edge my bet, one C H system and one hot water system.
Although it a long time ago that i fitted them, Andrews gas water or alike heaters were extremely quick to heat water. Positioning is most important, as in the event of a problem, servicing etc access without disturbing the tenants is paramount. Also the charges for up sizing the water main are far from cheap. Finding room at say the rear of the property and constructing a plant room against the building to house water heater and possibly a break tank holding water for both hot /cold and pumped. If the area is converting to flats/rooms mains water pressure will get worse.
Your existing boiler will take care of heating.
What ever you do please remember any excuse not to pay rent should be expected. Invest wisely.
Good Luck

I often suggest an electric shower if people have more than one bathroom, always handy should anything happen to the hot water system.

Sounds like the OP is against the idea of electric mate.

You need a Heating Engineer with Commercial experience to advise you properly.

In my opinion you would be better off paying for someone to design and specify.
