Planning a Heating Modernization – Why Prepare Your Home Before the Heating Season?

Replacing an old heat source with a modern air-to-water heat pump is one of the most important investment decisions for a single-family homeowner. Regardless of whether you currently heat your building with a solid fuel boiler (coal, wood, pea coal) or a gas boiler, thoughtful planning before the first frosts arrive helps you avoid unnecessary rush and heating downtime. A well-prepared installation ensures stable and efficient system operation throughout the entire winter.

Transitioning from traditional heating to an air-to-water heat pump system requires a proper engineering approach. It is not just about physically placing a new unit, but about thoroughly analyzing the building's thermal needs and adapting the entire domestic plumbing and electrical systems. Below, we present a complete breakdown of the installation stages and advise on how to prepare your property step by step for the upcoming heating season.

Step 1: Initial Analysis and Professional Building Audit

Every successful heating upgrade begins with reliable calculations. At example-shop.com, we do not size equipment "by rule of thumb" based solely on square footage. Two 150 m² homes can have completely different energy demands depending on thermal insulation thickness, window types, and ventilation methods.

The first stage is a free consultation and initial qualification. During the interview, we ask about key building parameters:

• square footage and year of construction,
• type of heating (surface/underfloor heating or radiators),
• current heat source and annual fuel or gas consumption.

Next, a site visit and on-site audit are conducted. A specialist calculates the building's actual heat demand, checks the condition of the internal plumbing, verifies electrical service capacity, and identifies the optimal location for the outdoor unit. It is worth noting that at example-shop.com, the audit is completely free if you choose us for the installation.

Step 2: Precise Sizing and Concept Preparation

Based on the collected audit data, the appropriate unit capacity is selected. For a typical single-family house, heat pump capacity usually ranges from 6 to 12 kW. Correct sizing is crucial: an undersized unit will fail to heat the home during severe freezes, while an oversized unit will short-cycle (frequently turn on and off), shortening compressor lifespan.

You receive a detailed offer including:

• exact scope of installation work,
• selected air-to-water heat pump model,
• capacity of the buffer tank and domestic hot water (DHW) cylinder,
• schedule and binding project completion date.

Keep in mind that the prepared quote is binding and valid for 30 days, and we prepare an initial cost estimate within as little as 48 hours of your inquiry.

Step 3: Preparing the Home Space and System

Before the installation crew arrives on-site, the work area must be properly prepared. Before the heating season, focus on two areas: outside the building and in the boiler room.

Preparing the Location for the Outdoor Unit

The heat pump's outdoor unit extracts energy from ambient air. It requires a stable foundation – it is mounted on a specially poured concrete pad or an appropriate wall bracket. It is important to ensure unobstructed airflow around the unit and proper drainage for condensate produced during system operation.

Modernizing the Boiler Room and Internal System

Switching from an old boiler to a heat pump involves modernizing the boiler room. The indoor unit, buffer tank, and DHW cylinder are installed in place of the old boiler. If the house was previously heated with high-temperature radiators, we also upgrade the radiator system for low-temperature operation as part of our services, allowing the equipment to achieve maximum efficiency.

Step 4: Heat Pump Installation (2–3 Business Days)

The installation process itself, carried out by professionals, runs very smoothly and typically takes 2 to 3 business days. The example-shop.com team consists of 9 qualified installers holding the necessary F-gas certifications and electrical qualifications up to 1 kV, ensuring complete safety and standards compliance.

Installation work includes:

• positioning the outdoor unit on a foundation or wall bracket,
• installing the indoor unit in the boiler room,
• hydraulic connections (including integrating the buffer tank and DHW cylinder),
• refrigerant and electrical connections,
• installing necessary safety fittings and filters.

Step 5: Commissioning, Configuration, and User Training

After completing mechanical and electrical work, a key step follows – initial startup and detailed system configuration. Operating parameters are tailored to the building's characteristics and household preferences.

During commissioning, installers set:

• Heating curve: the relationship between outdoor temperature and the temperature of water supplied to the heating system. A properly set heating curve ensures thermal comfort without wasting energy.
• Flow temperature: matched to underfloor heating or radiators.
• DHW operating modes: domestic hot water heating schedules.

Once the equipment is configured, the homeowner receives comprehensive training on using the wall-mounted controller and mobile app, enabling convenient temperature control from anywhere.

Step 6: Paperwork, Subsidy Documentation, and Service Support

Choosing a comprehensive service means you do not have to worry about paperwork. We prepare a complete set of technical and handover documents required for subsidy applications under programs like Clean Air or My Heat, and we assist in completing the forms correctly.

Operational peace of mind is backed by a 5-year workmanship warranty on installation and a manufacturer warranty on the unit itself (typically 5 to 7 years with regular servicing). We also provide annual maintenance inspections, and during the heating season, we guarantee a service response time of up to 48 hours.

How Much Does Heat Pump Installation Cost?

Investing in heat pump heating depends on the scope of work and chosen equipment. In our offer, the costs are as follows:

• Replacing only the heat source without major modifications to the internal system – from around 7,900 USD gross.
• Complete installation of a 7 kW heat pump including a DHW cylinder and buffer tank – from around 10,400 USD gross (prices before subsidies).
