Magnacleanse flush your central heating system

MagnaClean is a magnetic filter designed to maintain and protect all domestic central heating systems from the damaging effects of iron oxide & sludge build up. This protection lasts throughout the lifetime of the boiler and helps to reduce central heating energy bills by up to 6%.

Foster Plumbing & Heating Ltd will always recommend a MagnaClean magnetic filter for your pressurised central heating system.

The objective is to catch and remove deposits of iron oxide sludge, rust and any other magnetic debris from the radiators and pipe work and restore a system with circulation problems or boiler noises caused by the murky water and corrosion deposits.

A permanently installed MagnaClean Filter can remove these deposits and the problems that they cause, keeping your boiler and central heating system running at maximum efficiency.

Once you have a Magnetic filter installed on your boilers central heating circuit the system can then have a MagnaCleanse central heating system flush. A MagnaCleanse magnetic flush is a new flushing process designed to clean and protect all domestic central heating systems from the damaging effects of iron oxide sludge build up.

A MagnaCleanse flush delivers an extremely effective solution because it not only removes just as much sludge from the heating system. It also provides ongoing lifetime protection with the installation of a MagnaClean domestic filter.

Depending on the size of your system, the process enables us to carry out a routine MagnaCleanse system flush in a shorter time than power-flushing providing a potentially more productive and affordable flushing solution.

Not only does it flush the system, it provides a more intense deep clean using hot water along with specialist chemicals for ongoing protection for the boiler with the installation of a Magnetic filter. While power flushing can be quite effective, it is a fact that the build up of iron oxide will be an ongoing issue within the system.

Foster plumbing installed a new boiler and also recently changed radiators for me in my home. On both occasions they were reasonably priced and reliable and while working they were tidy and efficient. Would definitely recommend them to family and friends.

Underfloor heating made easy

Foster Plumbing and Heating Ltd install all types of underfloor wet heating systems.

Underfloor heating provides the most comfortable even warmth of any heating system. It is economical to run and virtually maintenance free.

The Speedfit system, which can be supplied and installed by us, has water being pumped from a boiler to a pump pack, where it is mixed to approximately 50°C then distributed via a manifold to heating circuits made using Speedfit Barrier Pipe. The pipe is laid in concrete or suspended just below the surface of the floor.

In concrete floors, the pipe is laid on insulation and then covered with a screed on which can be laid almost any type of floor covering.
 For timber floors, spreader plates are laid between the joists and the floor decking or on the underside of the floor. Speedfit Pipe is pushed into the grooves on the plates.

The floor area is typically warmed to between 25°C and 28°C, providing an even distribution of heat at only slightly higher than room temperature. The system is controlled by one or more thermostats, which signal the Pump Pack when heat is required.
