Hi, could you send me the plans, wiring diags and photos of energysavingexp immersion idea.

Just got a 4 KW solaredge PV system and we already have a GSH pump which has a 3/6KW immersion as a back up to heat water and or provide heat.

This sounds perfect if it can be used without giving the heatpump a fault condition, the heatpump pulls about 2.2KW when active and provides heating and hot water, the later seems to have priority as when hot water is used the heat pump will kick in to boost the temp back up then revert to heating if required, a system that will turn the immersion off if heat pump or any other device turns on would be an advantage.

Thanks

John

Hi legoman
having a 4kw solar system fitted tomorrow and would like to be able to maximise full potential with your immersion saver idea if you would be so kind.
Many Thanks

Hi

think carefully

even if you have a 4kw system your immersion heater is 3kw. You VERY rarely have surplus energy to use the immersion.

SO you have to buy a 1kw immersion element for the hot water tank (3 times as slow to heat up) and get that installed AS WELL as buying and installing all the electronic jiggery pokery this thread istalking about.

you have to buy the 1kw element so that you are in an energy surplus position to make it worth using.

How much will all that cost? and how much will you save?

also remember that to heat water buy electric costs 3x as much as per gas to do the same job. So you have to be VERY sure that your new electric based solution is only on at the right times AND you have to never really want to use the immersion as the main heat source as a 1kw element will be too slow.

i was going to do it all but decided against.

don't get carried away like i nearly did
