Designers of industry leading energy efficient heating solutions
Introducing the Water Waiter
The Water Waiter is an innovative, domestic water heating solution that intelligently steps in to instantly supply or top up water temperature where a shortfall exists. Installed upstream and inline on the hot water supply, the unit is silent, unobtrusive and extremely compact. The Water Waiter can be used in multiple situations, but its real value comes to the fore when specified as part of a central plant or district heating system.
Traditional Communal Heating System
Traditionally, communal heating and hot water systems have been structured around a shared central supply with gas being the primary source of energy. As a means of better controlling energy distribution in multi dwelling developments, architects and design engineers are increasingly specifying heat interface units as part of a system configuration. In addition, as building regulations tighten and more energy efficient initiatives come online, heat pumps are fast becoming a preferred alternative solution to gas. However, despite the many advances in heat pump technology, they regularly fall short and during periods of peak demand, fail to generate the heat required. The result is costly and space consuming gas fired central plant is still required as a means of back-up and top-up. In addition, even when specifying advanced HIU technology, primary circuit temperatures still need to be kept relatively high to cater for the peak periods of hot water demand. This is ineffective, inefficient the leads to the potential of buildings over-heating.
Heating System including the Water Waiter Solution
By specifying Water Waiter units in each dwelling downstream of the HIU, instant hot water of the desired temperature is always guaranteed. If low temperatures are detected, the Water Waiter steps in and simply tops up the temperature, but does so only for the period of demand. When the taps turn off, the Water Waiter’s heating operation immediately returns to standby keeping energy consumption to a minimum. Significantly, this intelligent functionality now means system primary temperatures no longer need to be kept constantly high, purely to service the irregular demand for domestic hot water. Temperatures can be reduced to as low as 45 degrees reducing heat loss, energy consumption and operating costs. Furthermore, lower primary temperatures require less heat energy from the heat pumps. By reducing this demand to a threshold where the heat pumps no longer need additional support, gas fired plant can be eliminated from the design configuration saving significant infrastructure costs.
