Owr Aga is producing more hot water than we need can I add a towel rail or gravity radiator from the hot tank?

Answer 1

I really don't think Michael H has a clue what he is talking about. If the Aga was installed correctly, there should have been a heat leak radiator fitted to the system when it was installed.If one is not fitted, it can certainly be done retrospectively, ensuring that where the branches are installed to feed the new radiator, do not allow the pipework to dip on the way to the radiator. You are relying on thermosyphonic action to circulate the water and the equivalent head difference between flow and return is about ¼" water pressure. Fitting the radiator will not affect the temperature, flow rate or condition of your hot water but will give you, normally, a lovely warm bathroom.

Answer 2

only if its in-line. In parallel ( like central heating ) you would have the potential for static warm water, not what you want coming out of your taps 6 months later.

Of cause this means the hot water tap temp will be lower and you couldn't turn if off, and it will lower yout hot tap pressure. In all, a very poor "last chance" rather than a "planned solution".

Maybe its better to fit a smaller jacket in the AGA or a larger water tank ?

I'm suprised its producing too much hot water, most don't produce enough. Remember to think about the summer, i assume you've got immersion elements for the summer ?

toast on the AGA this morning....lovely.

Answer 3

I don't see why not - we have a central heating style radiator in our bathroom that is connected to the hot water tank for when our Rayburn produces more heat than is needed.

Best thing would be to talk to a heating engineer or plumber as they will be able to advise you on any restrictions or special things that you would need to consider.

Answer 4

No.
There is a danger of tainting the water, i know you do not drink hot water from the tap but there is always the dish washing clothes etc.
Heating has to be a sealed system.
