Home/Aerothermal/Boiler-to-Aerothermal Conversion
Aerothermal · Conversion
Boiler to aerothermal conversion in Valencia — retire gas without losing a day of heat.
We replace your gas or diesel boiler with a heat pump: hydraulics adapted, emitters verified radiator by radiator, old plant removed — from €6,990, with the switchover planned so the house never goes cold.
In plain terms
A conversion is not an installation plus demolition.
The craft is in the sequence: audit what your radiators can do at lower temperatures, adapt the hydraulics around the pump, switch over in a planned window — and only then remove the old boiler, flue and tank properly.
Full conversion, old boiler removed
Typical switchover — often none at all
Versus burning gas for it
No flame, no flue, no CO risk
Why VELTORRA
What careful conversion looks like.
Emitter audit first
Each radiator checked for low-temperature duty before we quote.
Hydraulic adaptation
Flows, volumes and controls rebuilt around the pump.
Clean removal
Old boiler, tank and flue removed and disposed of properly.
Gas closure guidance
We advise on ending the gas contract once you're pump-only.
Winter-safe scheduling
The switchover is planned so the house never goes cold.
How it works
From audit to an empty flue.
Audit
Emitters, hydraulics and electrical supply reviewed as found.
Quotation
Conversion scope itemised — including removal and disposal.

Pump installed alongside; switchover in a planned window.

The price
The whole conversion, one written figure.
From €6,990 including removal and disposal of the old boiler. If any radiators need upsizing, they appear as separate lines in the quotation — never as surprises on site.

Questions, answered
Asked before hiring us.
Will my radiators work with a heat pump?
Many will — Valencia's mild winters help. We audit each radiator's output at lower temperatures first and tell you in writing which stay, which change, and what that costs.
How long is the house without heating?
Usually between none and one day: everything is prepared alongside the running boiler, and the switchover happens in a planned window.
What happens to the old boiler?
We disconnect, remove and dispose of it properly — and cap the flue and gas line ready for the contract closure.
Is diesel (gasóleo) conversion possible?
Yes. The process is the same, plus tank decommissioning — which we quote transparently as its own line.
What does conversion cost?
From €6,990 including removal and disposal. Emitter changes, if needed, are listed separately in the itemised quotation — the figure is fixed before work starts.
