What is Calor Gas Central Heating Installation Cost?

Installing Calor gas central heating may be your best option for many reasons if you don’t have access to mains gas in your property. Before you can go about choosing your heating system and look into the different options though, you should get a handle on the installation costs. In this guide, we’re going to run through everything you need to know about Calor gas central heating installation costs in the UK.

Understanding Calor Gas Central Heating Systems

Calor gas central heating is powered by liquefied petroleum gas (LPG) stored in an outside tank or cylinder. It works in the same way as a natural gas central heating system but is fueled from a different source and uses slightly different equipment. A Calor gas heating system will include an LPG boiler, radiators, pipework and controls as well as bulk storage tanks or cylinder storage equipment.

The main benefit of Calor gas central heating is that it can provide heating and hot water for properties that are off the mains gas grid, such as those in rural locations. If you’re interested in installing an LPG-powered system, you might also like to know that it is a cleaner-burning fuel than oil, so LPG central heating is a more environmentally-friendly option.

Modern Calor gas central heating systems provide high levels of efficiency with many rated at 90% or above. This means that more of the fuel you pay for is converted into heat for your home, so you’ll be wasting less energy and have more control over long-term running costs.

Factors Affecting Calor Gas Central Heating Installation Costs

Property Size and Layout

The overall size of your property is one of the most significant factors influencing LPG installation costs. Larger homes not only require more radiators but also need more extensive pipework to distribute heat effectively. This, in turn, often leads to a need for larger boilers capable of heating more substantial areas. 

For example, the cost of equipping a three-bedroom house with an LPG heating system will naturally be higher than that for a one-bedroom flat, due to the need for additional radiators and more complex pipework.

The property’s layout also plays a crucial role in determining the installation cost. A home with multiple floors or a complex layout may require more labour hours to install pipework and radiators in hard-to-reach areas, thus increasing the overall project cost.

Boiler Selection and Specifications

LPG boilers come in various sizes and efficiency ratings, with prices varying accordingly. Combination boilers that provide both heating and hot water tend to be more expensive initially but can save space and reduce installation complexity. System boilers require separate hot water cylinders but offer better performance for homes with higher hot water demand.

High-efficiency condensing boilers cost more upfront but deliver better long-term value through reduced fuel consumption. Premium brands with extended warranties and advanced features command higher prices but often provide greater reliability and performance over their operational lifetime.

Storage Options and Requirements

The decision between opting for bulk tank storage or cylinder storage has a significant impact on LPG installation costs. Bulk tanks offer the convenience of larger fuel storage and can potentially reduce the cost per unit of fuel. However, the upfront cost of purchasing a bulk tank is higher than that of cylinder storage. Underground tanks also cost more to install compared to above-ground tanks, primarily due to excavation work and additional safety measures.

Cylinder storage systems generally have lower installation costs but may lead to higher running costs over time. The number of cylinders required will also factor into the overall cost, as it is based on your specific heating requirements and how long you want to go between cylinder changes.

Existing Infrastructure

Properties with existing central heating systems may have lower installation costs if the existing radiators, pipework, and controls can be reused. However, older systems might require upgrades to work efficiently with modern LPG boilers, potentially increasing costs.

New installations in properties without existing central heating require complete system design and installation, including all pipework, radiators, controls, and safety systems. This represents a more substantial investment but provides the opportunity to design an optimal heating system for your specific needs.

Cost-Saving Strategies for Calor Gas Installation

Timing Your Installation

Installation costs can vary throughout the year, with potential savings available during quieter periods for heating engineers. Summer installations often cost less due to reduced demand, while avoiding peak winter periods can help secure better pricing and faster scheduling.

Planning installations well in advance allows time to obtain multiple quotations and negotiate better terms with suppliers and installers. Rush installations during cold weather typically carry premium pricing due to high demand and urgent scheduling requirements.

Comparing Quotations and Suppliers

Obtaining quotations from multiple suppliers and installers helps ensure competitive pricing and allows comparison of different system designs and specifications. However, the cheapest quotation isn’t always the best value, particularly if it involves lower-quality equipment or less experienced installers.

Consider the total cost of ownership including equipment reliability, warranty terms, ongoing maintenance requirements, and fuel efficiency ratings when comparing options. Premium equipment with better efficiency ratings often provides better long-term value despite higher initial costs.

Government Grants and Incentives

Some government schemes provide financial assistance for heating system upgrades, particularly in rural areas or for energy efficiency improvements. Research available grants and incentives before committing to installation, as these programmes can significantly reduce overall project costs.

Local authorities sometimes offer additional incentives for clean heating technologies, including LPG systems that replace older, less efficient heating methods. Check with your local council about available programmes and eligibility requirements.
