How complex a heating system is this?

john_cappa

House with 14-18 rads

One solid fuel stove with back boiler heating 7-9 rads
Another fuel stove with boiler connected to the other 7-9 rads
OFCH connected to all 14-18 rads
Solar panels for hot water

Certainly doable. First consideration would be that you require a solar cylinder with 4 coils sized to meet the hot water needs of the property which will be decided in turnby your panels. Then you are going to have to size the stoves to match your heating needs for each zone and size the oil boiler to cover all. You will probably need to compromise a bit but you should be able to size everything so that its economical to run.

wouldnt be that bad.

if it was me i would connect all heat sources to a thermal store such as the oil boiler, stove 1, stove 2 and the solar panels and then you can take heat from the thermal store to your different rads when you need it.

this would mean that you could have your heating system open vent, and then have you plumbing at mains pressure.

Ok thanks. Was just curious if it was an overly complex system for an the average plumber. Not really sure if that is the system best suited to my needs yet.

getting vent pipes to the attic from 2 stoves could be a problem depending on house layout

2 stoves a lot of work needed to keep them stoked

What do you mean venting pipes? is a chimney not all it needs?

Another method is using a system link see

If it was me doing a new install I would use this system.

Connect each heating boilers too it and then have each circuit from the systemlink zoned for several circuits all controlled by programmers and room thermostats. Then you would be able to heat different zones using different boilers, if you size each zone for the heat load of each solid fuel boiler and an oil boiler sized to heat the lot it would work fine. The ideal and cheaper would be to just use one large boilered solid fuel boiler and oil and solar panels.
You would still need to have gravity heat leak radiators in the event of a powercut.

You might aswell be speaking another language. I just dont have the time to do the required reading!

the pipes from the boiler of the stove must be rising toward the expansion tank...
if your pump fails or powercut,and the fire is at full beans, the hot water from the boiler must be able to naturally rise upward (convection) through the pipework.


do a google on 'open vented' central heating
