Hi everyone,

So here is my next challenge at home - underfloor heating. I know that the sq/m panel takes about 180w, but what I would like to know is:

I have 2 bathrooms and a passage of approximately 55sq/m of tiled floors. I have a 3Kw inverter with a 2.76Kw lithium 100Ah battery. Currently I have only essentials connected.

Do I need to go solar if I want to use my underfloor heating during loadshedding, cause this Winter in Cape Town is a freezer!!!

I know... Winter..... minimal sun = minimal charge. What will my solutions be please? Bigger batteries?

Looking forward to your input.

 

Regards

Just high-level: 55sqm x 180W/sqm   = 9.9kW, call it 10kW demand, and a further 2.4kW for household loads - let's say 2x8kW off-grid inverters in parallel, and around 25kWh of battery storage depleted over 2 hours of loadshedding. I suppose you could power underfloor heating from batteries if money was no object, and charge it from grid, but most folks would probably have to get by with lower-powered space heaters. Or blankets.

 

Inverter Aircons x3 might be a better call?
