Practical guides on heat pumps, refrigerants, solar thermal and hot-water storage — written for installers, distributors and project engineers.
Sizing a pool heat pump comes down to surface losses, season and cover. This guide gives kW-per-m³ rules of thumb, a heat-up formula, an inverter vs on/off comparison and running costs.
Read articlePV-T hybrid panels produce electricity and heat from the same square metres of roof. Here is how they work, where they pay off and what to check on the datasheet.
Read articleThe flat-plate collector is the workhorse of solar water heating. This guide explains what is inside, how to read η0, a1 and a2, what Solar Keymark certifies and when to use glycol or drainback.
Read articleThe storage tank decides how much hot water you get, how much heat you lose and how well a heat pump or solar system performs. This guide compares the four main tank types and gives sizing rules.
Read articleThe revised EU F-gas Regulation removes high-GWP refrigerants from small heat pumps from 2027. Here is how R290 and R32 compare and what buyers and distributors should plan for.
Read articleAn air-to-water heat pump delivers three to five units of heat for every unit of electricity. Here is how the cycle works and how to compare COP, SCOP and energy-label figures properly.
Read articleSend us your heating load, hot-water demand or pool volume and our engineers will propose a matching heat pump, tank and collector configuration.
