Heat Pump Installation Price

The heat pump installation price is not a single figure — it's made up of several components, each of which varies according to the building, system type and existing infrastructure. This overview covers the main cost factors and provides indicative price ranges to help you better understand what to plan for in your budget.

What affects the heat pump installation price

The heat pump installation price is determined by five main factors: the chosen system type (air-to-air, air-to-water or ground-source), the heated floor area and required capacity, the existing heating system type (radiators, underfloor heating or air), installation complexity, and additional work — pipe replacement, thermal insulation, electrical wiring renewal. For the same home type, the price difference can reach several thousand euros if in one case the existing infrastructure is compatible with the heat pump, but in another it requires substantial modification.

Heat pumps differ in price already at the unit level. An air-to-air heat pump has the lowest price, an air-to-water heat pump is mid-range, while a ground-source heat pump installation is the most expensive. This page covers what each cost component actually includes.

Unit price

The price of the unit — the heat pump itself and its components — makes up the largest share of the total budget. Typical ranges in Latvia:

• Air-to-air heat pump: €1,200–€4,000 per unit depending on the number of indoor units and capacity.
• Air-to-water heat pump: €4,000–€8,000 for the outdoor unit and indoor unit with controls.
• Ground-source heat pump: €8,000–€14,000 or more for the unit together with the ground heat exchange system.

The price is influenced by the manufacturer, capacity (kW), seasonal coefficient of performance (SCOP), the range of built-in features (inverter technology, hot water preparation, natural cooling) and additional components — buffer tank, hot water tank, additional circulation pumps. Well-known brands cost more, but installation and quality requirements should be comparable.

Installation work

Installation labor costs include securing the outdoor unit to a base or wall brackets, installing the indoor unit or module, connecting the system and commissioning. Air-to-air heat pump installation usually takes one or two days, air-to-water system installation — two to five days. The labor price also reflects the specialist's qualification: heat pump installation requires appropriate certification and a permit to work with refrigerants.

Hydraulic work

Hydraulic work is the most significant part of air-to-water and ground-source heat pump projects. It includes pipe connections between the heat pump and the heating system, installing a buffer tank (which levels out fluctuations in heat demand), connecting the hot water tank, mounting collectors and distribution manifolds, and installing safety groups and expansion tanks. For buildings with existing radiators, the hydraulic scheme may require adjustments — for example, mixing valves for low-temperature operation. Hydraulic work can amount to €1,000–€3,500 of the total air-to-water installation cost.

Electrical work

A heat pump needs a secure electrical connection matching the unit's capacity. Smaller air-to-air heat pumps are fine with a 230V connection and a suitable fuse, while higher-capacity air-to-water and ground-source systems usually require a three-phase connection (400V). Electrical work includes running cables from the electrical panel to the heat pump, installing separate fuses and residual current protection, and — if the existing panel is outdated — a panel upgrade. If the home has old electrical wiring, the electrical work portion can reach €500–€1,500.

Groundwork

Ground-source heat pumps have the largest amount of groundwork. There are two main types: vertical boreholes (up to 100–150 m deep) and horizontal collectors in trenches. Borehole costs in Latvia are approximately €3,000–€6,000 depending on depth and ground conditions; multiple boreholes or higher capacity increase costs. Horizontal collectors are cheaper but require a larger land area and deeper trenching. Groundwork makes up a significant share of the total ground-source heat pump price.

Commissioning

After installation is complete, the system must be commissioned. This includes charging the refrigerant (if not pre-loaded at the factory), a system leak check, configuring control settings, adjusting heating curves and hot water temperature, and efficiency and safety tests. Commissioning is usually included in the installation price, but requires a qualified specialist and sufficient time — which affects the overall labor cost.

Example scenarios

To make the indicative prices more tangible, let's look at three typical scenarios. These are approximate price ranges — the actual price can vary depending on the building's condition and the chosen manufacturer.

In the first scenario, an air-to-air heat pump provides heating and cooling for a single room or apartment without water-based heating. In the second, an air-to-water system connects to the existing radiator system and also prepares hot water. In the third, a ground-source heat pump with a vertical borehole serves a larger home with the highest seasonal efficiency.
