Viessmann Vitovolt 300 connects heat and power ecosystem

Viessmann’s Vitovolt 300 solar PV system makes it easier for homeowners to cover as many of their electricity needs as possible through renewable energy.

The photovoltaic solution comes with a 15-year product guarantee and incorporates a modular package of accessories that fit together. The result is an ecosystem that tailors to the needs of individual households, which can include sustainable heating and electric vehicle charging, if desired.

The Vitovolt 300 package is quick to install thanks to its plug-in solutions for electrical connections and fully wired matching components. Power storage can be added and all power flows monitored through Viessmann’s Energy Management System.

The PV package is also ideal for use with a Viessmann heat pump, enabling householders to generate electricity for use both as energy and heat, reducing running costs of the heat pump as well as energy costs for the entire home.

All elements are controlled via the Viessmann One Base control platform, which, via the ViCare app, enables users to view and optimise the use of their selfgenerated energy, whether it’s for domestic electricity consumption, storage, heat or mobility.

Sales director Chris Johnson says: “The Vitovolt 300 offers a great foundation for UK homes to transition to renewable technology for heating and motoring. It’s a very attractive option for homeowners looking to reduce their reliance on energy companies while also increasing the sustainability and value of their property.”

Salamander unveils water boost for high-demand properties

TankBoost is an easy-to-install, single-unit solution that ensures water performance remains at optimum levels even in large, multi-storey homes.

It delivers flow rates up to 80L/min and pressures up to 3 bar, so that even in the busiest homes showers, taps, toilets and more can be used at the same time.

The latest product in Salamander Pumps’ expanding MainsBooster range, TankBoost combines a cold water storage tank and an integral pump. The stainless-steel pump is submerged within the tank, which makes for quiet operation.

TankBoost has been designed to meet the water pressure and flow needs of domestic and light commercial installations, with four tank sizes available ranging from 100L to 450L. Additional storage tanks are also available to increase capacity for large properties or those with particularly low incoming flow rates.

TankBoost will overcome insufficient water pressure and flow in combi or unvented systems.

Technical director Gareth Richards says: “It’s a stand-alone, cost-effective solution that can be trusted to ‘run the show’, working hard to meet the water performance challenges that often occur when multiple outlets are running at once, eg, in larger, multi-storey properties, such as extended homes, HMOs, social housing settings, hotels and B&Bs.” www.salamanderpumps.co.uk/ tankboost provides a PV output of 4kWp, producing around 3,800kW/h per year, well over the typical annual UK four-person household consumption level of 2,900kW/h, according to Ofgem.

Any unused power can be stored in batteries or exported to the grid. If combined with a battery, EV charger and heat pump, where 100 per cent of self-generated power can be used by the household, a system this size can generate an annual electricity saving of around £1,140. This brings a return on investment for the solar PV system of around 10 years.

Larger packages offer greater savings, as well as sufficient electricity for bigger families and providing more power for heat pumps and electric vehicles. www.viessmann.co.uk

All elements of the package are covered by a 15-year product guarantee and full manufacturer support.

Mitsubishi Electric adds pre-plumbed cylinders

Mitsubishi Electric has a new range of domestic hot water cylinders to complement its residential heat pumps.

The unvented plug-and-play Ecodan R32 cylinder comes ready to install in eight standard and slimline variants in capacities of 150L to 300L. It includes pre-plumbed components such as pumps, filters and valves, reducing the overall installation time.

It is MELCloud-enabled, giving users control and monitoring, and the optional flexible two-zone spacing heating control provides improved comfort and reduces energy use.

Senior product manager Robert Taylor says: “We wanted to raise the bar with our new pre-plumbed cylinder. It’s been designed with intuitive installation connections in mind. With refined component design, performance has been improved so that it provides efficient and rapid heating of water. In addition, it comes with premium-quality insulation to reduce heat loss and running costs.” les.mitsubishielectric.co.uk/ ecodan-phase2
