REHAU has provided a
portfolio of pipework solutions to help deliver a district heating programme at
Piperdam – a luxury resort situated on the banks of Loch Piperdam, near Dundee.
Piperdam is an
award-winning resort set in 650 acres of Angus countryside. Located just 10
minutes from Dundee and 20 minutes from Perth, the resort has a number of
self-catering lodges, sleeping from 2-12 people, as well as restaurant and
leisure facilities on site.
Six years ago,
Piperdam’s owners collaborated with a local installation company – Hydroscot
Energies – on an energy strategy for the resort. Piperdam is off the mains gas
grid and was reliant on expensive alternative fuels, such as LPG and Kerosene,
so the owners were keen to find more sustainable and cost-efficient methods of
heating the tens of holiday lodges located on the site.
Scott Gaffney, owner
of Hydroscot Energies, said: “Piperdam has more than 80 holiday lodges, some
privately owned and some available for holiday lets, all with a requirement for
space heating. To meet this demand in the most cost-effective and sustainable
way, we looked into various forms of renewable energy systems, but the most
suited to the project was a series of district heating networks powered by
several large biomass boilers in conjunction with a Biogas Combined Heat and
Power Plant (CHP).”
Hydroscot Energies
recommended a phased programme of installations, starting with three networks
to provide heating for 70 holiday lodges. Each network would be powered by a
biomass boiler ranging between 200kw to 1MW. The main commercial complex
complete with Swimming Pool, Spa, Gym, restaurants and bars was powered by the
CHP.
To transfer the heat
from the plant rooms to the lodges, Scott required pre-insulated pipework. As
the lodges are spread across a large area, the pipe runs necessary were quite
considerable in places, so he needed a product which would minimise heat losses
as much as possible to ensure the efficiency of the system was upheld.
Scott got in touch
with REHAU about its pre-insulated pipe range. He had found a few other
suppliers, but REHAU was the only one with a UK base and he felt this was
critical to the smooth running of the installation programme.
Scott said: “A lot
of the pre-insulated pipework suppliers are based in Europe, and I was
concerned that this would cause us some difficulties in terms of stock and
access to customer support so when we saw REHAU were based in the UK, they
seemed to be a better fit for us and the project. Our REHAU regional sales
representative ensured we had a good supply at our local wholesalers, plus he
was on hand to answer any questions or queries we had, which was really useful
as we hadn’t worked with REHAU products before.”
After consulting
with REHAU on which products would be best for the district heating, Scott
specified RAUTHERMEX and RAUVITHERM pipework for the Piperdam job.
RAUTHERMEX is a
PE-Xa pipe suitable for a variety of low carbon heat installations and
featuring high performance PU foam, which makes it ideal for large district
heating installations over long distances where minimising heat losses is
critical. Scott specified the RAUTHERMEX for the spine of the district heating
installation at Piperdam, taking the heat directly from the biomass plant room
towards the lodges.
RAUVITHERM pipework
was then used to transfer the heat from the RAUTHERMEX pipe to individual
lodges. RAUVITHERM is also suitable for use in district heating, biomass,
biogas and heat pump applications, and is currently the only PE-Xa district
heating pipe manufactured in the UK, which saves an estimated 29% on Co2
emissions annually.
Scott added: “By
using the RAUVITHERM for short runs and the RAUTHERMEX over the longer
distances, we’ve been able to play to the strengths of each pipe and deliver an
abundance of heat to each lodge in the most efficient way.
“Both pipe product
types have been really easy to install too, which makes things better for us.
We are all quite efficient with the bespoke installation tools now!”
Piperdam is now
under new ownership, but the new managers want to continue with the energy
strategy implemented by Hydroscot Energies. Further expansion of the resort is
planned, with as many as 50 additional lodges added to the site in the next
phase, so the network will be expanded as required to meet the needs of the
park.
As well as the
district heating pipework, Scott also specified REHAU for an underfloor heating
project also carried out under the energy strategy works. Seven kilometers of
REHAU pipework was fitted to provide underfloor heating in the resort’s newly
built activity centre, which is used for events, conferences, concerts and
leisure activities for children and adults.
Steve Richmond, Head
of Marketing and Technical at REHAU, said: “District heating is growing in
popularity and can be used for many different applications to provide energy
efficient heat to multiple end users. It was a great choice for the Piperdam
project, as its unobtrusive for guests and can be cost-effectively added to
over time as more lodges are built.
"We are very
proud to have provided pipework solutions for the various installations at the
resort and are delighted to hear that our UK-based team has gone the extra mile
to deliver great customer service and support to Scott, who was new to REHAU and
our products.”
