Spirotech expands pressurisation range

Spirotech has added to its SpiroExpand range of pressurisation solutions designed to improve the efficiency and lifespan of heating and cooling systems on light commercial and renewable installations.

Currently available in five sizes, from 4 litres up to 25 litres, the pressure expansion vessel with fixed gas filling features a bellows membrane, which prevents the system water from coming into contact with the sheet metal wall of the vessel. This helps to reduce corrosion inside the vessel and can maintain optimum pressure up to five times more efficiently than expansion vessels with a standard flat membrane.

The pressure relief valve is located on the front of the unit for easier servicing and maintenance and the vessel comes with a built-in bracket for ease of installation.

Area sales manager

Dave Goodyer says: “This newest addition to our SpiroExpand range is designed to really simplify installation and maintenance for the installer, while also providing long-lasting results for the end user, at a crucial time when improving efficiency is more important than ever before.” www.spirotech.co.uk

TrustMark app helps consumers understand home improvements

TrustMark has created a free ‘one-stop shop’ home improvement app, aimed at helping people to better understand the process, requirements and considerations around having home improvement work carried out in their property.

The Home Improvement App will help to broaden their knowledge and confidence in dealing with and asking questions of tradespeople, particularly when it may be their first experience of doing so.

Viessmann increases output range for Vitodens 050-W

Viessmann has added a 35kW model to its Vitodens 050-W combi range. The new addition provides domestic hot water output from 2.9kW to 35kW and heating output from 3.2kW to 32kW, with a modulation range of 1:10 for increased seasonal efficiency.

The Vitodens’ MatriX-Plus burner with Lambda Pro combustion-control system provides high efficiency and low emissions, giving an ErP efficiency rating of 92 per cent (Class A).

Wi-Fi inside enables out-ofthe-box commissioning via Viessmann’s ViGuide Mobile app, while the user has full control of their heating using the ViCare app.

“The new higher output and increased flow rate offer a very attractive boiler at a mass-market price, for installers and customers looking for Viessmann quality and reliability, and offer increased hot water comfort for one-bathroom properties,” says marketing director Darren McMahon. “It’s ideal for both the specification sector and retrofit installations.”

Weather compensation can be incorporated with the addition of competent tradespeople, agreeing a contract and what to expect, project timelines, example costs, planning permissions, building regulations and insurance requirements, through to health and safety considerations.

TrustMark CEO Simon Ayers says: “We wanted to provide a tool that homeowners could use wherever they were, to help them ask appropriate questions and provide relevant information about the work they want done and how to go about things.” an inexpensive outdoor sensor. The in-built WiFi connects the boiler to the ViCare app even when the boiler is installed with third-party controls. This will ensure the boiler receives software updates, similar to other connected devices, enabling fault diagnostics and aiding the ongoing service and maintenance regime. www.viessmann.co.uk

The app is free to download: search for TrustMark on app stores.

The boiler is certified for a blend of 20 per cent hydrogen and up to 20m for horizontal and vertical flue systems.

Modutherm adds monobloc commercial heat pumps

The AW Monobloc range of commercial heat pumps from Modutherm is designed to offer powerful heating, cooling and hot water outputs for a wide range of applications, including residential apartment buildings, schools, offices and hotels.

There are three models –30kW, 45kW and 90kW – which can be cascaded in up to 16 units from one controller, providing a maximum combined output of 1,440kW.

With an A++ energy efficiency rating and a CoP up to 5.06, outputs can be adjusted automatically according to heat demand for optimum system efficiency. Enhanced vapour injection (EVI) technology stabilises the output and minimises energy consumption.

Nano-coated condensers enable faster water drainage from the condenser surface, reducing ice formation and defrost times. All models come with a five-year warranty on the compressor and a three-year warranty on parts. www.modutherm.co.uk
