Heat Pump Installation

Ground source heat pumps use pipes which are buried in the garden to extract heat from the ground. This heat can then be used to heat radiators, underfloor or warm air heating systems and hot water in your home.

A ground source heat pump circulates a mixture of water and antifreeze around a loop of pipe – called a ground loop – which is buried in your garden. Heat from the ground is absorbed into the fluid and then passes through a heat exchanger into the heat pump. The ground stays at a fairly constant temperature under the surface, so the heat pump can be used throughout the year – even in the middle of winter.

What Are The Benefits?

An air source heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside. It gets heat from the air even when the temperature is as low as -15° C. Heat pumps have some environmental impact as they need electricity to run, but the heat they extract from the ground, air, or water is constantly renewed naturally.

Project Description

Client:  Commercial Customer
Location:  Northumberland
Product:  Worcester Bosch 400kw Cascade

Our latest installation. A powerful but compact and energy efficient multi-boiler ‘cascade’ system using some of the latest Worcester-Bosch boilers. Their compact dimensions make them especially suitable for installations where space is restricted (such as in period properties) and for larger heat demands. They’re perfect for both large domestic and commercial applications such as this one.

The Challenges

You need to be a highly qualified and experienced specialist plumber and heating engineer with multiple qualifications to carry out commercial gas work. That’s why we’re here ????

All of our recommended boilers offer a flexible and cost effective solution to the energy efficient provision of heating and hot water in commercial premises. Moreover they are all cost-effective to service and maintain. In this instance the Worcester Bosch boilers we installed were easily combined (typically they can be installed in-line or back-to-back) and setup with a simple to use interface.
