Choosing an air source hot water heat pump cylinder can sound complicated, especially if you are not knee deep in the water heating jargon. This comparison data sheet helps cut through the noise, and it quickly becomes clear that Project CURV is the standout option when compared with Aquathermica, Atlantic Calypso, Dimplex Edel, and Mixergy iHP.
What is an Air Source Hot Water Heat Pump Cylinder?
In simple terms, this type of cylinder uses heat from the air to warm your water. It is designed to be more energy efficient than traditional systems, helping to lower running costs while still delivering reliable hot water for everyday use.
Easy Wins on Efficiency and Performance
Project CURV delivers a strong coefficient of performance of 3.2 at 7°C. That means it produces over three units of heat for every unit of electricity used, which is impressive and reassuring for homeowners new to heat pump technology. It also heats a full cylinder in just under seven hours, faster than most of the alternatives listed, so hot water is ready when you need it.
Lower Running Costs You Can Actually Feel
One of the biggest concerns for customers is cost. Project CURV is estimated to cost just £0.66 to heat a full cylinder from 10°C to 55°C. When you compare that to Aquathermica, Atlantic Calypso, or Dimplex Edel, CURV is clearly the most budget friendly to run. Over months and years, this can make a noticeable difference to household energy bills.
Quiet Enough to Forget It Is There
Noise matters more than you might think. Project CURV operates at just 36dB, making it the quietest cylinder in comparison. Other models can reach 50dB or more, which is a big jump. CURV does its job quietly in the background, without becoming an unwelcome house guest.
Project CURV is Built for the Future, Not Just Today
Project CURV uses R290 refrigerant, which is more environmentally friendly than the R134a used by several competitiors. It also includes CURV HP-M7 corrosion protection for added durability and is fully compatible with PV solar systems, making it a smart choice for homes looking to future proof their heating setup.
The Clear Choice Made Simple
When you break it all down, Project CURV offers the best balance of efficiency, cost savings, quiet operation, and long term reliability. For anyone new to air source hot water heat pumps, it is the easiest recommendation to make, and the hardest one to beat.
