Step-by-Step Guide to a Successful Heating System Install

Installing a new heating system can be one of the most important decisions you make for your home’s comfort and energy efficiency. From selecting the right heat source to completing the final commissioning, each step plays a crucial role in ensuring your system runs smoothly and keeps your home warm for years to come.

At Wells Spa Plumbing & Heating, we know how daunting this process can seem, which is why we’ve put together this simple step-by-step guide to help you understand the process of a successful heating system installation. Whether you’re building a new home or upgrading an old system, this guide will show you what to expect at every stage.

1. Deciding on the Heat Source

The first and most important decision in your heating system installation is choosing the right heat source. This will determine how efficiently your home stays warm and how much you’ll spend on energy bills.

Gas Heating

Gas boilers are a popular choice for homes connected to the gas mains. They’re cost-effective and provide reliable heating for homes of all sizes. If you’re looking for a traditional yet efficient option, a gas boiler may be your best bet.

Heat Pumps

If you’re looking to reduce your environmental impact, heat pumps are an excellent alternative. They extract heat from the air or ground, making them much more energy-efficient. Although they typically require a higher upfront investment, they can offer significant long-term savings on energy bills. It is also worth noting you will need a bit more outdoor space for heat pumps to be a viable option. If you are interested in heat pumps, check out our sister company Wells Renewables. 

Electric Heating

Electric heating systems can be a practical solution for homes without access to gas. Options like electric radiators or underfloor heating are less disruptive to install, though they may have higher running costs. A heating engineer can help you assess which system suits your home’s specific needs.

2. Heating Design and Heat Loss Survey

Once the heat source has been selected, the next step is designing the heating system. This is where a heating engineer will perform a heat loss survey to determine how much heat is required for each room.

Sizing Radiators or Underfloor Heating

Based on the heat loss survey results, your radiators or underfloor heating system will be sized to ensure maximum efficiency. Radiators must be appropriately sized to heat each room effectively without wasting energy.

Planning Pipework Routes

The pipework routes are planned during this stage to ensure hot water flows efficiently from the heat source to the radiators or underfloor system. Careful planning ensures that pipework remains hidden within the walls or floors, keeping your home neat and tidy.

3. Installing First Fix Pipework

After planning, it’s time to install the first fix pipework. These are the pipes that will run behind the walls and under floors, delivering hot water throughout your heating system.

A professional heating engineer will make sure the pipework is installed with precision, as any mistakes at this stage could be difficult and costly to fix later.

4. Testing After First Fix

Once the pipework is installed, it’s time to test the system for leaks. This crucial step ensures the system’s integrity before moving on to the next stage of installation.

Pressure Testing

The system is pressure tested to check for leaks or weak points in the pipework. This ensures everything is safe and efficient before moving forward. Many heating system maintenance plans include regular pressure tests to keep everything running smoothly after installation.

5. Second Fix: Installing Radiators and Heat Source

With the first fix complete and tested, it’s time to install the radiators or underfloor heating and connect the heat source. This step ensures your home will be heated efficiently.

Radiator Installation

Radiators are installed in each room based on the design and heat loss survey. Proper radiator installation is crucial to ensure that each room is heated efficiently and that your system remains energy-efficient.

Connecting the Heat Source

Once the radiators or underfloor heating system is in place, the heat source, whether it’s a gas boiler or heat pump, is connected. This final connection is essential to ensuring the system delivers heat effectively throughout your home.

6. Filling and Commissioning

Once everything is installed, it’s time to fill the system with water and commission it to ensure it’s operating efficiently.

System Commissioning

Commissioning involves running a series of tests to check the system’s temperature, pressure, and overall performance. A heating engineer will ensure everything is functioning correctly and optimised for long-term performance. Regular heating system maintenance is recommended to keep the system in peak condition.

7. Handover to the Homeowner

The final step is the handover. During this stage, your heating engineer will walk you through the system, explaining how it works and answering any questions.

Warranties and Documentation

At this point, you’ll receive all the necessary documentation, including warranties for the heat source and any key components. Understanding your system’s warranty and the required maintenance schedule will help keep your heating system running smoothly for years to come.
