1. Flat solar water heater is a metal pipe structure. It has thermal efficiency, large capacity, being pressure-bearing and anti-air drying. Water heating in the copper tube, so the quality is stable and reliable;
2. Free maintenance, service life is as long as the architecture; With double circulatory antifreeze ability, it is suitable for use in different regions;
3. It is easy to install, beautiful and environmental protection. There is almost no fault;
4. Being split designed, it has an elegant appearance; With split installation, it can be hung on balcony, window cornices, wall or roof;
5. High absorption rate: α S≥ 92%, significantly better than the vacuum tube collector, low-emission rate: Eh≤ 10%, daily average thermal efficiencyη D≥ 55%.

The running cost of a Lead Tech air source heat pump is:
1/4~1/6 of a gas water heater;
1/4~1/5 of an electrical water heater;
1/2~2/3 of solar auxiliary energy consumption.
