Product advice
Promasol
Promasol is one of the small group of Spanish solar thermal brands that EnviroCare specifies into new builds and major refurbishments where the CTE HE-4 building code requires a renewable contribution to domestic hot water. The collectors are made for the Spanish climate, the controllers handle the high-irradiance summer behaviour the coast throws at them, and the systems are sized to deliver between 60 and 70 per cent of annual hot water demand on a typical Costa del Sol villa. We have specified Promasol on coastal projects since the CTE building code came into force in 2006.
About the brand
Promasol is a Spanish manufacturer of solar thermal collectors and complete domestic hot water systems, based on the Iberian peninsula and supplying the residential and small commercial markets. The brand specialises in flat-plate selective collectors and thermosiphon systems sized for one to four-bedroom houses. The advantage of a domestic specialist for Costa del Sol installs is the same as on the heat-pump side: the technical support speaks the language, the parts and certification pipeline runs through Madrid and the systems are designed for Spanish irradiance and water chemistry from the start.
The range we fit
We fit two main configurations. Forced-circulation systems mount the collectors on the roof and the storage tank inside the property, with a controller and pump driving the glycol loop. These are the standard fit for villas where the technical area is in a basement or utility room and a tank on the roof is not practical. Thermosiphon systems mount the collectors and the tank together on the roof, working on natural convection without a pump. These are the fit for townhouses and single-storey homes where the roof can carry the tank weight and the visual is acceptable. Tank capacities run from 150 to 300 litres, with one to three flat-plate collectors depending on demand.
Where Promasol fits and where it does not
Promasol is the right call for new-build villas and major refurbishments where CTE HE-4 mandates a solar contribution to domestic hot water. It is also a sensible retrofit for owner-occupied homes where the roof has good south or south-east aspect, the household runs the hot water hard, and the owner wants to cut the gas or electricity bill on the back of Costa del Sol irradiance. It is the wrong call for an apartment in a community block where roof access is shared and any solar install needs the community's approval, which often is not forthcoming. It is also the wrong call for a low-occupancy holiday home where the unused hot water sits in the tank and creates legionella management headaches.
What the install includes
A standard Promasol install covers structural check on the roof load capacity, fit of the collectors with proper flashings and corrosion-resistant fixings, the glycol primary loop with controller and circulation pump, the storage tank with a backup electric immersion or gas heater integration, sensors on the collector and tank, full commissioning with system pressure and antifreeze concentration set, and the CTE HE-4 paperwork lodged for building sign-off where the install is part of a renovation. The F-Gas work where any heat-pump element is integrated runs through a certified engineer. Owners get the manufacturer warranty plus the EnviroCare three-year parts and labour warranty on top.
