Designed for the UK climate come rain or shine

Installing a Hyrax system will reduce your energy consumption and significantly reduce your carbon emissions.

Fossil fuels damage the atmosphere and affect our climate by destroying the ozone layer. The more we can do to reduce this, the better for us now and for future generations.

HYRAX CO 2 COMPARISONS CO2 calculation Power consumed x Conversation factor Gas 64.5 x 0.215 = 13.86 The figures of the CO2 for both gas and electricity respectively are based on the whole process, including fuel extraction, manufacture and distribution of the resource. In addition, the figure for electricity is for general grid produced electricity of which coal is the major fuel used. In spite of this, the HYRAX system uses vastly less energy than the direct electric heating and realises considerable savings on gas, whilst the CO2 is significantly reduced Therefore the amount of CO2 produced by the immersion heater would be 31.40kg An HYRAX system with a COP of 3.0 (300% efficient) would consume 58.05 / 3.0 = 19.35k Therefore the amount of CO2 produced would be 10.46kg An HYRAX system with a COP of 4.0 (400% efficient) would consume 58.05 / 4.0 = 14.51kW Therefore the amount of CO2 produced would be 7.85kg

HYRAX CO 2 COMPARISONS CO2 Comparisons Assumptions 1000kW natural gas produces 215kg CO2 Conversation factor 215 / 1000 = 0.215 1000kW grid electricity produces 541kg CO2 Conversation factor 541 / 1000 = 0.541 To raise the temperature of 1000 litres of water from 10°C to 60°C requires the following amount of energy: Q = MCΔT M = mass of water in kg C = Specific Heat Capacity of water = 4.18J/g°C ΔT = Change in temperature

HYRAX CO 2 COMPARISONS In this example Q = 1000 x 4.18 x 50 = 209,000 kJ / 3600 = 58.05kW A gas boiler of 90% efficiency would consume 58.05 / 0.9 = 64.5kW. Therefore the amount of CO2 produced by the gas boiler would be 13.86kg An electric immersion heater of 100% efficiency would consume 58.05kW. Therefore the amount of CO2 produced by the immersion heater would be 31.40kg An HYRAX system with a COP of 3.0 (300% efficient) would consume 58.05 / 3.0 = 19.35kW Therefore the amount of CO2 produced would be 10.46kg An HYRAX system with a COP of 4.0 (400% efficient) would consume 58.05 / 4.0 = 14.51kW Therefore the amount of CO2 produced would be 7.85kg

Hyrax technology will: provide “on demand” hot water warm your home more effectively than any other renewable source. It can be retro fitted to most existing radiator systems It is especially effective with underfloor heating.

If you have a swimming pool, Hyrax can heat your pool in summer and your house in winter.

SOLAR PANELS Consist of aluminium panels (1800 x 750 x 20mm deep) with special coating for maximum absorption and weigh less than 8 Kilo’s each. Each panel can operate in ‘portrait’ or ‘landscape’ orientation. Each panel can produce 1Kw of power. Uses R134-A refrigerant with evaporation occurring at approx -20ºC (depending on pressure).

SOLAR PANELS Maximum of 10 panels for single phase (up to 20 panels if using a soft start inverter). Over this will be 3-phase Sizing of a Hyrax system for heating and DHW, heat loss and relevant calculations are required to determine the number of panels required and in turn compressor size. For swimming pool applications it will be necessary to know the cubic capacity of the water, surface area and whether pool is indoor or outdoor. The system will work effectively for temperatures down to -5ºc

HYRAX SOLAR THERMODYNAMIC SYSTEM Typical Inputs/Outputs For a 6 panel system with flow at 60ºc and a 10ºΔt, input will be 1.75kW output 3.9kW (C.O.P. 2.25). with a flow of 35ºc, input will be 1.23kW, output 5.4kW (C.O.P. 4.46). For a 28 panel system at 60°c and a 10°Δt, input will be 7.42kW, output 18.60kW (C.O.P. 2.5). at 35°c, input will be 5.21kW, output 26.30kW (C.O.P. 5.05). These figures were compiled by Copeland Scrolls and don't take into account solar gains.

HYRAX SOLAR THERMODYNAMIC SYSTEMS C.O.P. Ratings will average between 2.1 and 5.3 with seasonally adjusted figures and depending on geographical location. The maximum pipe run between compressor and panel is 20m and all joints require to be silver soldered. Installation training courses are provided by PPL in York and are City and Guilds recognised. Additionally, all installers will be required to be ‘F’ Gas registered Heatpumps use ‘Copeland Scrolls compressors, except for the smaller Aqua system which uses ‘Danfos’.

Hyrax Solar are: Leading the way forward in solar technology for water heating Always there to offer advice and support

HYRAX SOLAR THERMODYNAMIC SYSTEMS Have been awarded an exclusive European patent for the rapid defrost of the system. Defrost is essential to prevent dangerous ice build up and to prevent compromising system performance. The Hyrax system reverse cycling in winter (defrost) only needs to operate for 2mins every 12hrs so efficiency is virtually unaffected. Note: In air source heat pumps reverse cycling can be 5-8 mins in any one hr, thus affecting system performance The Hyrax system is virtually noise free, no noisy fans etc.

CASE STUDIES Case Study 1. M.O.D. Near Swindon, 2 x systems System one – (Star System) 28 panels providing 500m² of underfloor heating. Included in the system is a 400ltr buffer vessel with 2 x 9kW 3-phase immersion heaters to provide back-up only. System 2- (Aqua system) for DHW 2 panels 1 x 500ltr cylinder, 1 x 6kW single phase immersion heater (for back-up).

CASE STUDIES Case study 2. Southend Council 2 x Systems 2 x 1950’s bungalows. Each have a 4 panel Hyrax Star System to provide for radiators and DHW.

CASE STUDIES Case study 3. New build property, Gloucestershire Hyrax Aqua 300 system, 2 x panels, slightly larger compressor (for quicker response) Normal Aqua system would consist of 1 panel combined with a 200ltr cylinder. Apart from this small system, all panels will be supplied in multiples of two.

COSTINGS For the 28 panel system approximate cost was between £15-16k (excluding tanks). The 2 x 4 panel systems were £3-4k (each). The Hyrax Aqua 300 system 4 x panels was approx’ £3.9k. These are supply only prices, installation prices are roughly 50% of supply prices. Although the systems will be economic in all locations they stand alone. They are extremely beneficial in remote locations where there is no piped gas.
