Daikin heat pumps

Daikin Altherma, built as one complete comfort system.

Enerus designs Daikin Altherma air-to-water systems around calculated heat loss, flow temperature, hot-water demand and the available plant space—then commissions the controls around the finished home.

Explore the system routes

A range to navigate—not a model to guess.

Select an option to understand its role. Enerus confirms the final combination from heat loss, design temperatures, hot-water demand, electrical supply, sound and siting.

  • Final output checked at the design condition
  • Hydraulics and electrical supply confirmed
  • Sound, airflow and service access assessed

The exact single- or three-phase model and available duty are checked against the property.

Domestic hot water

Integrated 180/230-litre and separate storage routes.

Daikin floor-standing indoor units are available with integrated domestic-hot-water storage, while wall-mounted modules can work with separate compatible tanks. ECH₂O storage is another system route on supported products.

  • Usable capacity and peak household demand
  • Coil duty and heat-pump reheat performance
  • Standing loss, immersion and pasteurisation strategy
  • Dimensions, pipework and service clearances

Controls and connectivity

The controller is part of the heating design.

Weather compensation, schedules and domestic-hot-water priorities are commissioned around the property—not left at generic defaults.

MMI user interface

The indoor interface supports guided commissioning, heating and hot-water setup, schedules and system information.

2

Madoka

Daikin’s compact wired room controller provides a discreet local interface on compatible system arrangements.

3

ONECTA

Compatible Altherma systems can be monitored and adjusted from Daikin’s ONECTA app when the required connection is fitted.

App and cloud services depend on compatible hardware, account setup, network coverage and the manufacturer’s current service terms.

The Enerus design process

One team from survey to support.

1

Calculate the home

Room-by-room heat loss, emitters, hot water, electrical supply and the proposed outdoor position are assessed.

2

Define the package

Outdoor unit, indoor module, cylinder, controls, hydraulics and installation details become one clear proposal.

3

Commission and support

Flow, heating curve, schedules and hot-water operation are set up and explained at handover.

Common questions

Daikin heat-pump FAQs.

What Daikin heat-pump ranges does this page cover?

The page explains Altherma 4 H, Altherma 3 monobloc, Altherma 3 H HT. Enerus confirms the current model and compatibility before quotation.

Which Altherma output does my home need?

Selection comes from room-by-room heat loss and manufacturer capacity data at the project design temperature and proposed flow temperature—not floor area or the model label alone.

How is the hot-water cylinder selected?

Enerus checks baths, showers, simultaneous use, usable volume, recovery, standing loss, dimensions, water pressure and service access.

Can a Daikin heat pump work with radiators?

Potentially. Existing radiators are assessed at the intended heat-pump flow temperature and upgraded where their available output is insufficient.

Can the system be controlled remotely?

Remote features depend on the selected controller, gateway, internet connection, firmware and service availability. The exact functions are confirmed in the proposed package.

Could the installation qualify for the Boiler Upgrade Scheme?

Eligibility depends on the property, installation, installer and scheme conditions current at the time of application.
