Frequently Asked Questions
A. Hot water requirements for commercial projects are typically calculated using CIBSE guidance to meet the required standards. We utilise BS EN806 and BS 8558 to help our customers understand their requirements and can provide suitable product options to meet those requirements.
A. In a word, yes. A packaged plate heat exchanger is a great replacement for a calorifier for the vast majority of applications.
A. Not entirely, but it will significantly reduce the risk if installed to supply DHW instantaneously due to the vastly reduced volume of water in the system when the storage element is removed.
A. Plate heat exchangers are one of the most efficient ways to transfer heat in the HVAC industry, in fact they are 99% efficient with only a 1% heat loss in most scenarios. Couple this with the most efficient pumps and control components available in today’s market and you have an unbeatable solution.
A. Packaged plate heat exchangers are typically installed freestanding in a plant room, and are connected via the 4 following connection points: Primary flow, Primary return, Secondary flow, and secondary return. Power is then supplied to the control panel and the unit is ready for commissioning and setup.
A. Packaged plate heat exchangers tend to cost more than standalone plate heat exchangers, but offer a wide range of benefits that a standalone plate heat exchanger simply can’t offer. They are also supplied with all the required pumps, valves and control components fitted to ensure optimum performance of the heat exchanger.
A. A calorifier is a storage buffer vessel that holds a body of water (most commonly DHW), and has an internal coil or similar heating element which circulates a primary heating circuit, designed to indirectly heat the body of water in the vessel.
