What is a Heat Pump ;

a Heat Pump is a mechanical device that allows the absorption of energy from the environment (low temperature) and its transfer to the space to be heated (higher temperature).

The pump can absorb heat from a cold environment, even several degrees below 0 as the medium for absorbing this energy (the coolant) is much colder than the environment (-80°C) when it is expelled at the expansion valve and converted into gas. This very cold gas absorbs energy from its less cold surroundings via an external exchanger with one or two fans, and is heated enough to raise its temperature significantly.

Thermodynamic natural phenomena through a sequence of cycles constantly transfer energy from the environment to the house, consuming much less electricity - which we can even produce ourselves!

What I get with a Heat Pump ;

Calculate your profit

A practical way of calculating the benefit of heating using a heat pump and photovoltaic is the following

Case 1

Heating Oil Use

With an average purchase price for winter 23/24, 1,000 litres of oil cost 1,300 € and yield 9,000 kWh of thermal energy.

Through a heat pump the same energy is produced from 3,000 kWh of electricity that costs about 500 €.

This energy is produced by
at a cost of 0 € a 2,2 PV system kW!

Case 2

Use of Natural Gas

With a price approach of 0.08€/kWh (charged like electricity, at a price per kilowatt-hour), if a consumer wants 9,000 kWh of thermal energy from gas, he will require 9,000*0.08= 720 € plus network charges (distribution, transport, taxes, etc.). The estimate is 15% below oil for this year, i.e. 1,100 €.

Through a heat pump the same energy is produced from 3,000 kWh of electricity that costs about 500 €.

This energy is able to produce
at a cost of 0 € a 2,2 PV system kW!

Free Sizing and Installation Study from Technimon

Study of home heating needs and how they are currently served.
Introduction of how these will be served via pump in the future.

With this study we use whatever heating infrastructure the house has and combine it with the pump to reduce costs with the lowest possible investment, but sufficient for quality heating!

How do I install a Heat Pump ;

A Heat Pump is very easy to install, with little plumbing and electrical interventions. There are of course some technical rules that must be applied.

A pump can be connected to a heating network in many ways:

Directly to the radiators

This is only advisable if the cross-sections of the existing network allow it or if we are building a new network.

Through inertia vessel

To cope with small heating network cross-sections, reduce the many on/off, which contributes to even more economical operation and longevity of the device, utilization of night-time electricity tariffs, etc.

To work with useful - if not necessary - hybridisations.

If we need to combine the pump with a second or third heating source (solar heater, oil or gas boiler, energy fireplace, etc.) that we have.

As a support to an underfloor heating system

It can be powered by a simple connection to the installation's electrical network. The power supply can be provided by any means such as: The grid itself, our own power from photovoltaic, with a backup generator, with a storage system, etc.

It can be managed remotely, online.

This also offers the possibility of immediate diagnosis of operational problems, immediate diagnosis of possible faults, etc.

In any case, the pump requires careful and appropriate sizing

and technically appropriate connection to the heating network.

How do I ensure the Heat Pump ;

In any electricity and heat generation construction it is particularly important to ensure that consumers are provided with services to support the continued operation of appliances and installations.

The heat pump does not require regular maintenance service apart from ensuring the cleanliness of the heating network - i.e. cleaning the filters. As an appliance, it is possible that it may be damaged over the years of operation.

So "Τεχνήμων", in addition to the warranty given by the manufacturer of the device, supplements your guarantees as follows:

2 Years Warranty

good functioning of the whole installation (hydraulic and electrical parts).

Maximum Performance

by changing the setting of the device, depending on the consumer's needs, either online or via a wi-fi network.


equipment and housing for one year.


the operation of the device forever. Telematic fault diagnosis.

Zero heating costs forever
with a PV and a heat pump!!!!

Technimon - which systematically deals with the installation of photovoltaic systems and energy saving - is able to dimension, cost and build a system that reliably meets your combined needs.
