Replacing your boiler with a heat pump in Ibiza

In short

Almost any boiler can be replaced by a heat pump, reusing much of the existing system. The key is knowing what water temperature your radiators or underfloor system need.

Author: Climai Group technical teamTechnical review: [DATO PENDIENTE: técnico RITE de Climai Group]Updated:

Is it worth replacing a boiler with a heat pump?

Generally yes, when the boiler runs on heating oil, propane or electric resistance, or when it is near the end of its life. The heat pump provides the same heating and hot water while buying less energy, and adds cooling if the emitters allow it.

What matters most in the decision:

  • What fuel you use today and how much you pay for it.
  • What emitters you have: underfloor heating, radiators or fan coils.
  • How well the house is insulated.
  • Whether other work is planned, such as windows, roof or façade.

The actual saving depends on each home. The calculator gives a first estimate and the technical study refines it.

What can be reused from the current system?

How do I know if my radiators will work?

A radiator gives less heat the cooler the water. The question is not whether the radiator works, but whether it gives enough heat at the temperature where the heat pump is efficient.

We check it like this:

  1. We measure each room and its heat loss.
  2. We note the type and size of each radiator.
  3. We calculate its output at the planned working temperature.
  4. If a room falls short, we propose replacing only that radiator or fitting a low-temperature one.

How does the work go, step by step?

  1. Site visit: we measure and check the system and the consumer unit.
  2. Study and quote: output, unit, cylinder and work required.
  3. Preparation: flushing the circuit and, if needed, electrical upgrades.
  4. Removal of the boiler, flue and fuel tank.
  5. Installation of the outdoor unit, hot water cylinder and connections.
  6. Commissioning: filling, bleeding, setting the heating curves and explaining how to use it.
  7. Registration: paperwork under the RITE.

What changes day to day?

  • No fuel to buy or deliveries to arrange.
  • Heating runs continuously and gently, instead of firing at full power and switching off.
  • Maintenance is different: periodic checks of the unit, filter and hydraulic circuit, with no burner or flue cleaning.

Frequently asked questions

Do I have to replace my radiators?

Not always. If they are well sized or the house is well insulated, they can work with cooler water. We check by calculating each radiator's output at the heat pump's working temperature.

What happens to the heating oil tank?

It has to be emptied, cleaned and made inert, or removed, as the regulations require. We include it in the quote if needed.

How many days will I be without heating?

It depends on the job. In a straight swap with the indoor system in good condition, the interruption is usually short. The quote states the timescale.

Can I keep the boiler as a backup?

It is technically possible (a hybrid system), but in Ibiza's climate a properly sized heat pump rarely needs backup. We assess it case by case.

Will I need more electrical capacity?

Sometimes. We check the contracted power and the consumer unit during the visit.

Are there grants for replacing a boiler?

There may be, depending on timing and the type of home. See the grants page, where each scheme shows its status and official source.
