Solar Hot Water Heating
Use the sun to heat water for your home, radiant floors, or pool — simple, reliable, and efficient.
How solar hot water works
Rooftop collectors capture the sun’s energy and transfer it to a heat-safe fluid. A pump moves that heat into a storage tank through a heat exchanger. Your taps, radiant floors, or pool then draw from that tank. When the sun’s not enough, your boiler or heater tops up automatically.
- Two main collector types: flat-plate (great all-rounder) and evacuated-tube (strong in colder/overcast conditions).
- Two main system styles: pressurized glycol (freeze-protected) or drainback (collector drains when off).
- Works with: domestic hot water tanks, radiant floor manifolds, pool/spa heat exchangers.
Why homeowners choose solar hot water
Let the sun handle a big share of your water heating — reduces gas or electricity consumption.
Summer: heavy lifting by solar. Winter: pre-heats incoming water so your boiler does less work.
Great for families, rentals, or suites that use lots of hot water; helps steady supply and recovery.
No added noise or duct dust; integrates neatly with existing tanks, radiant, or pool systems.
Roof or ground-mount; pairs with boilers or air-to-water heat pumps; pool/spa options.
Smart controller manages pumps and freeze protection; clear status and fault alerts.
