WATTS enriches its range of products dedicated to the implementation of air/water heat pumps in new builds and renovations

While the air/water heat pump market is falling slightly (-4,7%), after a year of strong growth in 2022*, the government's announcements aimed at increasing the MaPrimeRénov' scales from €1.000 to €2.000 in 2024 for the installation of a carbon-free heating system should revive it. It is in this context that WATTS, an expert in hydraulic systems for over 100 years and recognized for its anti-pollution and network security products, is expanding its “PAC System” offering with a new range of buffer tanks and a new separator. magnetic sludge.

A range of buffer tanks to save energy

Operating in addition to an existing hydraulic heating system, the new range of WATTS buffer tanks consists of three tank models, with a capacity of 25, 50 and 100 liters, dedicated to primary heat pump and heating systems. cooling.

Mainly made of a steel cylinder for optimal shock resistance and manufactured in accordance with directives 2014/68/EU and 2009/125/EC, WATTS buffer tanks are large water tanks which are placed between the heat pump and the heat emitters associated with it. The device recovers the excess calories provided by the heat pump to heat the water in the tank and then allows you to reuse what would have been lost by returning this stored thermal energy to the heating circuit. This limits the use of the heat pump and increases its lifespan by reducing the number of starts/stops of it or of the cooling unit, when rapid temperature variations occur.

Equipped with main connections and additional connections, protected by plastic caps during transport, they offer the possibility of adding accessories such as a thermometer. Easy to install, their maintenance is also simplified by direct access to the drain and the integration of a flexible hose for the 100 liter model.

Lined with 25 or 30 mm rigid polyurethane thermal insulation to limit losses, WATTS buffer tanks keep the heated water at the same temperature and thus contribute to reducing heating consumption and therefore saving money. energy. Enough to improve the energy performance of housing!

Technical characteristics : . maximum operating pressure: 6 bar. operating temperature range: -10°C to +110°C. exterior finish in satin smooth lacquered aluminum sheet. Weight: 8,5 kg, 13,5 kg, 26 kg. External diameter: 410, 325 or 460 mm. Total height: 450, 1000 or 950 mm (with feet for the 100 liter tank)

A new magnetic sludge separator for optimal protection of heat pumps

Essential to guarantee the proper long-term operation of heat pumps, the use of magnetic sludge separators in heating systems eliminate the deleterious effects caused by residues of earth, limestone, sand and ferrous metals present in thermal installations. They also prevent wear and damage to other components of the heating circuit.

To guarantee continuous protection of heat pumps, WATTS offers the new S360 magnetic sludge separator in composite body (reinforced PA 66 polyamide). Specially designed for heat pumps thanks to its high flow rate (5000 L/h), it retains impurities and prevents their circulation.

Delivered with plastic connections in DN 3/4'' and 1' and equipped with a 360° adjustable angle to adapt to all inclinations, they are easily mounted on the return circuit, with the body always in position vertical, upstream of the heat pump in order to protect it from the penetration of residues into the piping, particularly during the start-up phase.

Thanks to a metal clip for quick cleaning and a threaded tip for bleeding, maintenance is carried out in no time,

Technical characteristics: Usable fluids: water and brine Maximum glycol content: 30% Maximum operating pressure: 3 bar Operating temperature range: 4 to 90°C Particle separation capacity: up to 500 μm

By thus enriching its offer with buffer tanks and a sludge pot, WATTS offers installers a complete range of products to make air/water heat pump installations more reliable, worry-free and quick. Also the assurance for individuals of having a heating system that is both ecological and economical. A winning duo to combine energy efficiency and reduction of the carbon impact of housing!
