New headering service for ground source heat systems
Water & Energy Field Services now offer a headering up service for closed loop ground source heat systems.
The service is applicable from single borehole/loop to large commercial multiple loop projects delivering the ground array flow and return into the plant room.
We can provide a turnkey service or a pick and mix approach covering the following:· Header design & pipe sizing · Supply & installation of header pipe
· Electrofusion & butt fusion welding
· Trenching, sanding & backfilling
· Supply & installation of manifolds
· Pressure testing
· Sanitising
· Carrier fluid selection & filling
· Final connection to heat pump/s
Our engineers have extensive groundworks experience gained from the utilities sector and work to the following technical guides and standards:
· WIS 4-32 –08 (2002). Specification for fusion Jointing of PE pressure pipeline systems using PE80 & PE100.
· WIS 4-32-18 (2003). The choice of pressure rating for PE pipe systems
· BS ISO 12176-2:2008 Plastics pipes and fittings. Equipment for fusion jointing polyethylene systems.
· BS ISO 21307:2009 Plastics pipes and fittings. Butt fusion jointing procedures for polyethylene (PE) pipes and fittings.
· IGSHPA (2007). Closed Loop Heat Pump Systems, Design & Installation Standards.
· IGSHPA (1988) Guide to Installation of Closed Loop Systems.

Water & Energy Field Services keeps Nottinghamshire warm
Water & Energy Field Services have completed the installation of a bivalent heating system for a client in North Nottinghamshire. The ground array, designed to support a peak load of 17kW, comprised 3 x 90m boreholes drilled through the Mercia Mudstone Formation.
The boreholes were drilled using a small track mounted rig to minimise disturbance. The header pipe was trenched back to the plant room under the patio.
A Vaillant Geotherm heat pump was selected for the project and linked to a 500 litre buffer tank. The heat pump was integrated with the oil boiler and the bivalent system linked to the existing standard sized radiators
The system has been designed to use the existing oil boiler as the emergency back up and will engage if the heat pump can no longer maintain the desired internal temperature (20 - 21°C) i.e. it can no longer keep up with the heat loss from the building. However, the system has performed as expected with no input from the oil boiler even during the recent cold spell when the temperature outside reached minus 10°C !
Water & Energy Field Services continue to monitor the system remotely, with early data suggesting an efficency (COP) of between 3.5 to 3.9.
The client , Mr Wilkinson, said, “after 6 months of operation, through the coldest winter in 40 years, the system provided the warmth we needed when we needed it”.
£400 for your old boiler
Up to 125,000 households in England with working “G-rated” boilers can from today apply through the Energy Saving Trust for a voucher which will entitle them to £400 off the price of a new, modern “A-rated” boiler or a renewable heating system like a biomass boiler or a heat pump.
Ed Miliband of the Government said:
“The Boiler Scrappage Scheme will save around £200 off heating bills per year for families that are replacing their old boilers, and in total will save the same amount of carbon equivalent to taking around 45,000 cars off the road.
It is worth knowing that the scrappage scheme is in addition to any available grants for heat pumps.
How can you tell if your boiler is G-rated?
A good quick test for gas boilers is to see if it has a permanent pilot light -if it has then it is very likely to be a G-rated boiler. If it is gas fired and over fifteen years old it is likely to be eligible. If it is oil fired and over twenty five years old, it is likely to be eligible.

The UK suffered its coldest night of the winter so far on 7th January 2010 with temperatures plummeting to -22.3C (-8.1F) in a village in Sutherland in the Highlands. Overnight temperatures of -10C (14F) were widespread.
The extreme cold period has seen an increase in demand of gas for domestic heating, causing supplies to be restricted elsewhere.
The BBC reported that 27 firms - 12 in the East Midlands and 15 in the North West - switched to alternative fuels after National Grid told them to turn off their gas supply, with demand for energy soaring. At one point, 95 major firms were affected. Environment Secretary Hilary Benn insisted there were "plenty of supplies" of gas!
However, limiting supplies to firms to ensure adequate supplies for the rest of us suggests that demand could easily outstrip supply during very cold spells. This combined with our reliance on imported gas presents serious security of supply issues. It is likely that this situation will worsen as fossil fuel supplies dwindle
One option is to switch from gas or oil to a renewable energy source, such as ground source heat. When combined with a green electrical supply they provide a sustainable and cheaper solution to your heating and hot water demands.
One of the questions often asked about ground source heat and heat pumps is whether they can still deliver the required heating levels during periods of prolonged cold, to which the answer is YES, provided the system is properly designed.

Project manager job at Water & Energy Field Services
Working as an important part of a small team, the job will be office based although some site supervision and travel within the UK will be necessary. The role is an opportunity to develop within a new and growing company in the renewable energy sector.
The primary function will be to support the Directors, Senior Project Managers and Senior Field Engineers in project-related tasks including, but not limited to:
Liaison with clients and contractors
Providing cost estimates and compiling technical proposals
Production of as built drawings and and compiling of commissioning documents
Site surveys to assess ground conditions
Supervision of groundwork and drilling
Risk assessments and method statements
Management of suppliers
Cost control
Input into website content and marketing material
Management of MIS 3005 quality system
Ideally the candidate will have experience in the renewable energy sector, preferably with a knowledge of ground source heating and a background in geology or engineering is preferred.
A high level of computer literacy is required, with a knowledge of CAD an advantage but not essential. The ideal candidate should be a good team player, highly adaptable and possess excellent communication skills.
