Get a better angle on installation under the boiler

The Fernox TF1 Sigma UB Filter is a system filter that breaks from tradition by allowing horizontal installation at a 90° angle, directly under the boiler, close to the wall and with direct connections to the system. It is an easy to install option even in the most restricted of spaces and has been developed for use with concealed pipework.

The design of the filter means it captures the maximum amount of circulating debris possible. System water passes through the manifold into the filter’s main body, where the magnetic debris is transferred directly to the powerful, neodymium magnet. This protects the boiler, optimises boiler efficiency and prevents system breakdown. Installers will appreciate that the drain valve provides a robust service point that allows the filter to be emptied without the risk of spillage. It also acts as a convenient dosing point for the Fernox Express chemical water treatment range. As the system does not need to be drained down it helps to save time on site, so cleaning and dosing can take place in less than two minutes, making compliance with BS 7593:2019 as well as Part L of the Building Regulations simple.

Heating additive saves on energy

EndoTherm is an energy-saving additive that can be added to heating systems to enhance the water’s ability to transfer heat. The company claims up to 15% saving on heating costs in wet systems, which has been verified both in laboratory and in real-world use. It works by reducing boiler and transport losses, improving warm-up time, and minimising excessive heating. The liquid can be added to any closed wet heating system, domestic or commercial. The treatment is installed at 1% of water volume, so a typical house needs 500ml to 1 litre which can easily be installed through a filling loop, radiator or magnetic filter.

The return on investment is now typically less than 6 months, says the company, and it works as soon as it is installed, lasting for up to 10 years. The product is noncorrosive and is supported by major boiler manufacturers.

Clearing up the confusion: grey means heat pumps

In light of some confusion over incorrect specification of magnetic filters on heat pump installations, Inta has designed its IntaKlean HP Magnetic Air Source Heat Pump Filter in grey to distinguish it from the model used on gas boilers.

Inta MD Stuart Gizzi explains: “We’ve heard reports of breakdowns on heat pump installations because the wrong type of magnetic filter has been installed. It’s really easy to see how mistakes have been made, because the heat pump and gas versions look identical, made from robust black plastic.

“Luckily, the solution is just as easy. Change the colour of the filter body, to make it instantly recognisable as a heat pump fitment. So we are the first manufacturer to introduce the colour coded grey IntaKlean HP – a multi-layered direct filter, with high magnetic strength, designed and coloured especially for heat pumps.”
