Complete domestic and commercial hot water solutions — DHW tanks, buffer tanks, thermal stores and heat-pump hot water. AHHAC supplies the Latento WP-S stratified tank, Nexus tanks and the MAXA hot water heat pump range.
Hot water is where domestic and commercial hydronics meet. Whether it's a family of five or a 200-room hotel, the principles are the same: generate heat efficiently (heat pump, boiler or solar), store it intelligently (a well-stratified tank or thermal store), and deliver it on demand without running out.
AHHAC supplies a complete hot water package — the Latento WP-S stratified thermal store (which layers hot water at the top and cool at the bottom for maximum usable capacity), the Nexus DHW and buffer tank range (100 L, 200 L, single and twin-coil 315 L), and MAXA hot water heat pumps for the heat source. For larger commercial demand, see our dedicated MAXA HWA2 commercial range.
Domestic: a single DHW cylinder or thermal store (200-315 L) heated by a heat pump or boiler covers most homes. A twin-coil tank lets two heat sources (e.g. solar + heat pump) feed the same store. Commercial: cascaded heat pumps feeding multiple large stores, sized to peak simultaneous demand with redundancy. AHHAC sizes the storage to your draw profile and the heat source to your recovery requirement. For full commercial plant, see the MAXA HWA2 reversible chillers and heat pumps.
Stratified thermal store that layers hot water at the top and cool at the bottom — maximises usable hot water from a heat pump and smooths demand peaks. Ideal for heat-pump DHW.
Twin-coil cylinder lets two heat sources (solar + heat pump, or boiler + heat pump) feed one store. Also available single-coil.
Buffer tanks decouple the heat pump from the distribution system — reducing short-cycling and extending compressor life.
R290 monoblock delivering domestic hot water up to 78°C. Pairs with the Latento or Nexus stores for an all-electric DHW solution.
