EnviroCare has fitted and serviced solar hot water systems on the Costa del Sol since 1996. With the right roof position and storage tank, solar can cover a large part of a home’s hot water demand.
How solar hot water works
Solar collectors on the roof absorb heat from the sun. That heat is transferred to water stored in a cylinder, ready for showers, cleaning and general household use.
Most systems still need a gas or electric backup for colder days, periods of heavy use or properties with higher winter demand.
Gravity systems
A gravity or thermosiphon system has the storage tank above the collectors. Heated water rises naturally, so the system does not need a circulation pump.
This can be a simple, effective option where the roof layout suits it.
Pump-circulated systems
A pumped system places the tank away from the collectors and uses a circulation pump to move heat between the roof and the cylinder.
This gives more flexibility on properties where the tank cannot sit above the panels.
What EnviroCare checks
Before recommending a system, the survey needs to check:
- roof orientation and available space
- shade from walls, chimneys, trees or neighbouring buildings
- household hot water demand
- existing cylinder and pipework
- access for installation and future servicing
- whether a booster is needed
Servicing before summer
Solar hot water systems should be checked before the busiest months. A service can identify leaks, pressure issues, pump faults, scale build-up and tired insulation before demand rises.
Ask EnviroCare about solar hot water if you want to replace an older system, add backup heating or check whether solar is suitable for the property.
