Home/Aerothermal/Buffer Tanks & Storage
Aerothermal · Buffer & storage
Buffer tanks and thermal storage in Valencia — stability your heat pump can feel.
The right buffer stops short-cycling, protects the compressor and lets cheap tariff hours do the heavy lifting — installed and integrated from €790.
In plain terms
Small tank, long consequences.
A heat pump that starts and stops every few minutes wears out early and never reaches efficiency. A correctly sized buffer gives it room to run properly — and gives you a place to store the cheapest hours of your tariff.

The heat pump starts and stops constantly
Underfloor zones are small or numerous
Noise complaints trace back to frequent starts
You're on a time-of-use electricity tariff

Questions, answered
Asked before hiring us.
Do I always need a buffer tank?
No — and honest sizing sometimes says so. A well-matched single-zone underfloor system may not need one; small zones and radiator circuits usually do. We calculate rather than default.
Buffer tank or bigger hot water tank?
Different jobs: the buffer serves your heating circuits; the hot water tank serves your taps. They are sized separately — sometimes combined in one cylinder when space demands it.
What size do I need?
Enough volume for the unit's minimum runtime against your smallest zone — typically 50–200 litres. The calculation comes with the quotation.
Will a buffer save electricity?
Its first job is stability and equipment life. With time-of-use tariffs it also shifts consumption into cheap hours — a saving you can schedule.
Where does it fit?
Slim, tall formats fit most technical rooms and utility cupboards; we confirm exact dimensions at the survey before anything is ordered.
