USING BOILER CONTROLS THE RIGHT WAY AT RIVERSIDE CHILDREN’S CENTRE
Canterbury-based nursery Riverside Children’s Centre provides childcare and cooked meals for children aged 6 weeks to 5 years.
Philip Kiss, Building Services Engineer at Canterbury City Council, turned to Hamworthy Heating for a reliable and efficient solution to replace the existing heating and hot water system. The chosen products have already achieved cost savings of 16.7% after 7 months of operation.

Ian McGregor, Area Sales Manager at Hamworthy Heating, chose Hamworthy’s Stratton mk2 wall hung condensing boiler with stainless steel heat exchanger and a Halstock stainless steel indirect-fired water heater as an ideal replacement. The boiler delivers an output of 43kW, a high gross seasonal efficiency of 95.75% and features modern built-in boiler controls to supply heat and hot water the most efficient way. The boiler can supply heat for low to high demand flexibly and efficiently from 8kW up to 43kW.
The nursery has a water softener installed to prevent issues caused by hard water, such as limescale. However, softened water can be more aggressive, resulting in corrosion. That’s why a stainless steel boiler and water heater were chosen, as this material is resistant to corrosion. Riverside Children’s Centre has underfloor heating which can only take a maximum water temperature of 50°C to avoid structural damage to floors. To cater to those needs, a hot water priority strategy using the boiler’s built-in controls was set up: When required, the underfloor heating circuit is switched off and all power directed to hot water production at a higher temperature of 80°C in a lessefficient (non-condensing) mode. As soon as excess heat has been distributed around the separate hot water supply circuit, heating operation goes back to lower temperature high-efficiency (condensing) mode. This way, the underfloor heating circuit is protected from high temperatures and boiler running time in less efficient non-condensing mode is minimised.
