Holiday home switches from oil to heat pump


A working farm in the Cotswolds, which also operates five Airbnb holiday properties, has replaced oil heating in one of its larger cottages with a heat pump from Navien. The three-bedroom, three-bathroom property required a more dependable system to meet the demands of guests and maintain consistent heating and hot water throughout the year. Like many rural properties


without access to mains gas, the farm had relied on oil heating for many years. However, the existing boiler was no longer able to meet demand. After obtaining recommendations and quotations, the owners selected the Navien PEM750 17kW heat pump for the retrofit project. Installed outside the cottage, the


unit was fitted without disrupting the operation of the farm or guests

staying elsewhere on site. The changeover from oil heating was straightforward and the system has provided reliable performance since installation, particularly during busy periods when the property needs to be brought back up to temperature between bookings. The system can be monitored


remotely using the Navien Heat Pump app, allowing the owners to check performance and make adjustments. Navien says the PEM750 range is designed for retrofit applications and includes a seven-year parts and labour warranty.


Since the installation, the


owners report that the cottage has maintained consistent heating and hot water, while guest feedback has remained positive. The project demonstrates the use of a heat pump as an alternative to oil heating in a rural accommodation setting. By upgrading to the Navien


PEM750 heat pump, the owners have been able to future-proof their heating systems, improve day-to- day site operations and provide guests with a consistently warm and comfortable stay year-round. ◼ phamnews.co.uk/726/55


Waste water heat recovery cuts energy use by 80%


Wastewater heat recovery technology from Showersave is helping create a low- carbon, future-ready facility for Blairgowrie Community Recreation Centre. Developed by Perth and Kinross


Water-saving taps deliver reliability and durability


The family-owned Mortonhall Estate, located in Edinburgh, has evolved to include various facilities and services, including the largest touring caravan park in Scotland, which offers 575 touring pitches, 21 caravan holiday homes and eight wigwams. The facility features a number of


Delabie products, chosen by leisure and retail manager Kevin Wright for their reliability, water-saving and aesthetic advantages. “The Tempostop taps were the


first Delabie-DVS taps we installed in one of our park’s WC facilities,” says Kevin. “This was our first real test, and they have worked perfectly for six years without any faults or replacements.” Following their proven reliability


and durability across existing washrooms and shower facilities, Kevin now plans to specify Delabie-DVS in an upcoming


facilities block project. Water conservation is an


important concern for the estate, given the substantial number of taps, toilets, and showers across the park. Delabie-DVS products are designed to minimise water waste, contributing to significant cost savings and environmental benefits. With its automatic shut- off and adjustable flow rates, the Binoptic tap saves up to 90% of water compared to conventional taps. Highlighting the support


available from Delabie during the installation process, Kevin adds: “Direct communication and prompt assistance have been crucial to the project’s successful implementation. The support from Robbie, specification and sales manager for Scotland, and the technical team has been great.” ◼ phamnews.co.uk/726/58


Council, the £36 million facility located in the centre of Blairgowrie features a 25m swimming pool, sports halls, fitness suite, dance studio and a PE classroom for Blairgowrie High School students and the wider public. Constructed from cross-


Heating engineer Dan Davies from Lampeter, Wales, has been building a boiler room in his own home, ensuring that the finished project meets his own high standards. Part of his specification was a Stelrad Column radiator in the boiler room, in vibrant flame red (RAL3000), to make a statement as well as to provide comfort heating levels. “I’ve been really impressed


with Stelrad products,” says Dan. “I was fortunate enough to tour the factory last year, and it was incredible to see the full process – from raw materials, right through to manufacture, testing, painting, packaging and dispatch. The scale of it gives you real confidence in the quality of what you’re installing. “I’m a firm believer that you


get what you pay for, and that’s definitely the case here. We’ve used cheaper radiators in the


past, and the difference in quality is clear to see. Stelrad products are far superior in both build and finish.” He says the work involved in


building his boiler room has been a real labour of love, fitting it in around a busy workload: “I’ve been very particular about the products used, and the Stelrad radiator was an easy choice. It’s something I take a lot of pride in and often refer to as ‘my baby’!” ◼ phamnews.co.uk/726/56


Energy consumption is expected to be reduced by 80% compared to a typical leisure centre due to a range of innovative energy- saving technologies incorporated throughout. A key contributor to these savings


is the installation of Showersave’s WWHRS. By capturing heat from shower wastewater, the system preheats the incoming cold feed that refills the system. Blairgowrie opted to install


laminated timber and glulam, the building has strong thermal and acoustic insulation, ensuring a comfortable indoor climate.


College buildings success


A major energy refurbishment project carried out at a University of West London college has achieved significant improvements to the energy efficiency of both historic and contemporary buildings, replacing the complex’s gas- fired boilers with a district heating scheme fed by air source heat pumps. ESBE valves are playing a key part in the management of the heating and hot water supply. The year-long upgrade at


Ruskin College was led by Norfolk-based Finn Geotherm. Crucial to the success of the changeover has been the ability


of the company’s designs to manage the variation in supply temperature required for the individual heating and hot water circuits within the four buildings. Reflecting on the success of


the project, technical director David Alston says: “I have a long- standing relationship with ESBE and we’ve fitted thousands of their valves in different projects over the years. “We do so because of their build


quality and reliability while we were particularly keen on using the ‘rotary shoe principle’. This district heating system has a design SCOP of 3.83 and has run


reliably over the whole of the winter with only positive feedback from the college.” ◼ phamnews.co.uk/726/59


18 Showersave Blue QB1-21 wastewater heat recovery systems across the site, with each unit feeding two showers with sustainably heated water. With heat transfer through the copper pipe to warm the incoming cold mains water, the result is a 42% reduction in hot water demand, helping to save energy and make showering more sustainable. ◼ phamnews.co.uk/726/57
