144. Fundamental Requirements of any swimming pool • WATER HEATING Replenish pool water heat losses • AIR HEATING Replenish/maintain pool air above pool temperature • DEHUMIDIFICATION Remove moisture from pool hall air • FRESH AIR Ventilate at minimum acceptable rates to dilute CO & airborne chemical build up ( also to create negative pressure) • SUMMERTIME COOLING To remove solar heat gains

145. What do indoor swimming pools require? 1. A pool temperature of between 28ºC and 30ºC (for leisure use) to make swimming pools suitable for swimmers 2. Pool hall air at 1ºC above pool temperature to minimise evaporation of pool water to minimise transmission loss to air to provide a comfortable condition for occupants 3. Relative Humidity of 55-65%RH to prevent condensation and damage to building to provide a comfortable condition for occupants 4. Ventilation at 10 litres/sec/person or 3 litres/sec/m2 pool area Dilute CO2 build up reduce airborne chemical build up eliminate odours

209. Ground Source Heat Pumps • Amplified/ Upgraded - Heat from the Earth! • Available EVERYWHERE in the UK • Totally Renewable • Totally Sustainable • Replenished naturally via Solar energy • Proven technology

210. Types of Ground Systems • Open loop • Water extracted from ground and discharged back at second point • Closed loop • Water circulated • Evaporator installed direct in ground, refrigerant circulated

211. Loop Configurations

213. Ground Source Heat Pump with a swimming pool AHU

214. • GSHP providing LPHW at 55oC in place of conventional boiler • Output of LPHW coils reduced, usually flow temperature 80oC. • 50% of rated output!! • Need to check changed capacity against building and pool heat loads • Calorex are only company that can offer complete 100% heat pump only solution for an indoor pool • Good viable solution, particularly off gas network Ground Source Heat Pump with a swimming pool AHU

215. GSHP & Variheat

216. ASHP & Variheat

217. GSHP for Indoor Pool Water Heating • Operational heat losses of pool made up from recovered energy if using heat pump heat recovery AHU • Only water heat load comes from back wash of filters and dilution for chemical treatment • Heat up from cold done rarely • Cost prohibitive to size GSHP for rapid heat up time. • Limited usage if installed just for limited pool water heat load • GSHP combined with other loads e.g. pool hall air heating, main dwelling space heating would be OK

218. GSHP for Outdoor Pool • Summer Season; March - October • Use Air Source Heat Pump; e.g. Calorex 29 or 31 range • COP of GSHP fixed at 4 • COP of ASHP variable from 4 when air at 10oC to 6 with air at 25oC • Installation cost of ASHP cheaper than GSHP • Running cost of ASHP cheaper than GSHP • Conclusion - Install ASHP

219. Funding • Microgeneration Certification scheme - MCS – Approved product + approved installer – ASHP £900 – GSHP £1200 • CERT – Energy supplier • Carbon Trust Loan – Interest free loan over 4 years – Payback based on energy saving achieved

220. Summary • 1kWh of electricity can deliver over 4kWh of renewable energy from the ground • Proven technology with case studies to back up performance • The lowest running cost system for “off gas” network areas • Huge savings on running costs • Huge savings on CO2 emissions • Long life, low maintenance, sustainable technology.

221. Summary • Manufactured in UK by British Company • Designed specifically for UK Domestic market • Provides both space and water heating without the need for supplementary water heating • Works with under floor heating, radiators or pool units • Controlled using central heating programmer • Compatible with both new build and existing homes - dependent on thermal specification • Technical & Service support from existing Calorex field service engineers

227. Grouting

228. Grouting the Borehole

229. Horizontal Ground Loop • Requires more space • More suited to new build • Less stable ground temperature; can be less efficient • Cost saving if site contractor lays the pipes • 5kW = 2 x 40m trenches at 5m spacing

230. Horizontal Slinky

231. Horizontal Loops 25kW GSHP 8 x 50m trenches all 5m apart

232. GSHP System Characteristics • Building - Thermal characteristics and user load requirements for heating and DHW • Heat Pump - Output matched to load requirements of building • Ground Loop - Designed to provide renewable energy in line with requirements of the building load and heat pump
