Aqua Range Heat Interface Unit Why use Johnson & Starley HIU’s As market leaders and innovators Johnson & Starley have increasingly specialised in domestic heating. We helped to pioneer Warm Air Heating as the first popular domestic central heating system and became the market leaders which we still are to this day. Our strategy for success has been based on a strong product development program, listening to our customers and installers and utilising this feed back to complement our own technological and manufacturing capabilities. This has ensured that product designs incorporate user...

Instantaneous Hot Water Direct Heating Instantaneous Hot Water Indirect Heating Stored Hot Water Indirect Heating Instantaneous Hot Water Indirect Underfloor Heating

AquaTec Heat Interface Unit Johnson & Starley Heating Interface Units Energy efficiency and reducing carbon emissions are key factors when designing renovation schemes or new build development projects. As we know, the world wide Kyoto agreement which the UK government signed up to, has placed mandatory, strict demands on reducing greenhouse emissions going forward. Decentralised heating systems via Heating Interface Units, are an effective way of achieving this and offers many benefits to both the investor and the occupants. The HIU is a non fuel burning appliance and therefore does not...

AquaTec Heat Interface Unit The AquaTec twin plate HIU is specifically designed to be used where the hot water is required to be instantaneous and is supplied with an integral pump and expansion vessel. Two plate heat exchangers are used to hydraulically provide a break between the domestic water from the space heating water which is supplied directly from the central boiler plant. Advantages are:- Top connections Including Valves Bottom Connections Including Valves Metering & Billing Pressed Copper Fittings Clarity of primary and secondary circuits Primary and secondary circuits can be...

AquaTec Heat Interface Unit Stored hot water with indirect heating is used in systems where separation is required between the primary and secondary circuit. Stored hot water or instantaneous systems both have their advantages, however, the stored solution also reduces the need for higher boiler power and also reduces the size of the distribution network and pumps. The Johnson & Starley HIU can be used with almost any hot water cylinder or thermal store which provides the user with controllable heat and hot water comfort. Advantages are:- Top connections Including Valves Botton Connections...

Ultrasonic Heat Meter Fully electronic heat meter with ultrasonic technology to record energy and volume data. MID (measuring instruments directive) approved so suitable for billing. Can also be supplied with various remote communication systems such as Mbus and wireless Mbus. Differential Pressure Controller Ensuring constant differential pressure within the entire apartment installation or HIU depending on type, and optimum functioning of the control valves. This also ensures the system is automatically balanced. Plate Heat Exchangers There can be either one or two plate heat exchangers...

Pre-Payment Valve Where the energy usage is billed using a pre-payment option, the primary energy can be automatically shut off until further credit payment is made. Strainers Johnson & Starley HIU can be suppled with strainers in the primary flow and secondary return to protect the plate heat exchangers from system debris. Thermostatic Control Valve These are fitted into the primary circuit and are used to limit the temperature of the primary return, therefore increasing the efficiency of the system. Two Port Motorised Valves. These valves are used to stop the flow of primary water through the...

Aquair Water To Air Heat Interface Units The Aquair ‘Heat Interface Unit’ (HIU) is unique in its design and versatility and will provide all the benefits that centralised heating systems offer. There is no other product on the market that can replace a warm air heater in a single dwelling, fully utilising the existing warm air ducting, be integrated into a centralised heating system, run in conjunction with an existing wet system with the option of supplying unheated air for cooling purposes during warm weather conditions. Aquair HIU can be used with a vast range of heat sources such as...
