Unless hard water in your heating system is treated, scale builds up in the heat exchangers pipework and immersion heater elements. Only 1.5 mm of scale build up will increase your energy consumption by 12% per year.

This 10in Deluxe Housing system uses polyphosphate in a dilute form and acts as a sequester preventing precipitation of calcium scale as well as offering a level of protection against corrosion.

The polyphosphates forms bonds with the scale causing minerals, which make them more water soluble. The hard minerals remain in the solution as opposed to depositing scale on heat exchangers. This means that the treatment is permanent so storage of water in tanks and thermo stores remains protected at all times

These kits are easily installed just in front of the boiler on the cold water inlet feed or at the mains for whole house protection. 15 mm or 22 mm versions available. This unit has significantly lower running costs as the internal dispenser is refillable allowing you to buy Polyphosphate refills that contain more dosing capacity than disposable refill cartridges.

The Wrekin VIH10 is a deluxe filter housing with a built in Isolating valve with 3 Positions

Filter - filter in service

Off - Isolates water supply to tap for filter change

Bypass - Allows water flow without going through the filter

Installation notes

The VIH10 can be fitted on the incoming supply to a house or on the cold feed to a particular appliance. The choice of location is dependent on the type of cartridge being used. With this unit it is not necessary to fit isolating valves to allow cartridge change as the unit has its own non-return to allow easy filter change

Maintenance

Cartridges should be replaced in accordance with the individual chosen filters recommendation. However filter life is dependent on the quality of the incoming water and the amount of water used.
