Twin Plus Range
For clients who desire a higher degree of energy efficiency we have our TWIN PLUS RANGE of Water Heaters. These are basically the same as our TWIN RANGE, with a high-performance grade A gas fired boiler, but with the added benefit of having a Flue Gas Heat Recovery Device fitted as standard. This device extracts the latent heat within exhaust flue gas and stores it, to put it back into the cold feed to the cylinder when required, giving an even faster recovery during operation (see this link to principle of design). This design has given our clients proven savings in both fuel costs and carbon emission at a cost effect price.
This is a very compact freestanding unit making it ideal for water heater upgrades where fuel efficiency and environmental impact is a critical factor, giving the highest possible system efficiency variable up to 97% currently available. saving both fuel costs and reducing carbon emissions this is the most cost-effective method of incorporating recovered energy into a gas fired water heater.
As with the TWIN RANGE these units are constructed to the same high standards and design principle as our single units but with duplicate boilers, plate heat exchangers and destratification pumps serving a single standard 500 litre cylinder (other cylinder sizes can be provided) each boiler package can work independently of the other unit, giving a high degree of fault tolerance, we advise that the 130% fault tolerance rule is applied that is the total boiler power provide is 130% of the maximum required therefore if there is a fault on one boiler set, 65% of maximum demand can still be provided. A combined boiler outputs of 60, 80, 100, 140 180 and 230kW can be provided.
This is a flexibly designed unit consisting of three separate self-contained frames which can be configured in various footprint layouts to give flexibility in plant room integration. All interconnecting components between each frame is supplied to give easy site assembly.
Each frame is prefabricated and is delivered to site pre-tested it only needs the final connections to the existing services and commissioning, saving time and installation costs and the down time of the existing services.
If more efficiency is required, then please go to our recovery and renewable section in the website.
