Solar Hot Water / Heating Systems
SOLAR HOT WATER / HEATING SYSTEMS
Efficient Heat have been trained by Viessmann and Vaillant to install
solar systems. Being trained by leading solar
panel manufactures and being Corgi and IPHE registered means the
installation is easy and tuned for maximum efficiency so as
to take full advantage of free energy from the sun.
HOW SOLAR HOT WATER SYSTEMS WORK
"Solar panels can heat 100% of your hot water in the summer [with
temperatures reaching 180 'C] and save at least 60% of the annual
fuel cost for heating hot water (that's just the hot water part of
your fuel bill not the total fuel bill). Solar panels can
absorb direct and indirect energy from the sun even on dull
days and convert it into heat." Viessmann
Solar collectors hold water that gets heated by the sun. This water is pumped
in a circuit to a heat exchanger that transfers its heat to the contents of the
storage cylinder. The storage cylinder's heated water can then be used at various points of
access: baths, sinks etc., (see diagram) If the contents of the storage cylinder cools to
below a set amount a demand from the solar panel is requested to bring the heat
back to a desired temperature. If the solar panel is not producing enough hot water
to heat the contents of the cylinder the cylinder requests that a boiler produce
heat for a second heat exchanger in the cylinder. This backup method ensures you will always have hot water on demand
"Vitosol solar tubes can be sited almost anywhere on flat or
pitched roofs and walls. Individual tubes are rotated to best
capture energy from the sun's rays." Viessmann
BENEFITS OF SOLAR HOT WATER / HEATING SYSTEMS
"With rising fuel prices and increased environmental awareness,
solar panels are becoming more important as a means of heating
domestic hot water. Viessmann's highly efficient solar
collectors can provide all the energy you need for hot water during
the summer months, or 50-60% of the total annual
requirement." Viessmann
"...research has shown that solar panels for hot water can add
up to 10,000 to the value of a house." Viessmann
"For every detached house that installs solar panels, carbon
dioxide emissions are reduced by 3/4 of a tonne!"
Viessmann
By cutting emissions of carbon dioxide (CO2) the main greenhouse gas
causing climate change you are acting socially responsibly by using
energy in a sustainable and efficient way.
Power Flushing
POWER FLUSHING
Efficient Heat are Norstrom proflush approved power flushing operators. We can further
improve your heating system efficiency, reduce noise and ensure your heating
system runs smoothly by power
flushing the network of pipes and heating components. To improve the
process we use a magnetic filtration unit integrally located in the
power flushing machine. This magnet collects debris that is taken
out of the flushing process.
WHAT IS POWER FLUSHING
Power flushing forces water through a heating system which loosens
debris from the network of pipes and components. Adding a protective cleanser
to the process can improve the longevity of the your system and control any further deterioration.
Power flushing removes lime-scale, corrosion and improves the efficiency
of you central heating.
BENEFITS OF POWER FLUSHING
"All new systems should be pre-commission cleansed in
accordance with BS:7593 Benchmark. This ensures flux
residues, excess jointing compounds, mineral oil and other
contaminants that can be found in the system following installation,
and that can effect the performance of the system or cause component
failure, are removed." Fernox
"Without treatment, corrosion debris will accumulate in the boiler
causing increasing lime-scale deposits, reduced heat transfer
and up to a third of a fuel bill going to complete
waste." Fernox

formation of scale and sludge
* To inhibit the growth of microbiological organisms
* To maintain the engineering design specifications and energy

Condensing Boilers
CONDENSING BOILERS
Efficient Heat have been installing and repairing condensing boilers
for eight years. We are trained by Vaillant and Viessmann so we can
meet their exacting standards. To maintain the efficiency of boilers
we use a digital boiler analyser with several sensors to ensure
everything is working to peak performance. Efficient Heat's partner
company boilerreplacement.net specialises in the
installation, maintenance and repair of condensing boilers. We can carry
out gas safety checks, landlord certificates and provide you with a printed
copy of the readouts from our digital gas analyser.
WHAT IS A CONDENSING BOILER
Condensing boilers are more efficient than non condensing boilers
because they reuse heat that would otherwise escape through the flue.
As this reused heat cools the temperature drops to a level where liquid
water is formed. This cooled water is called a condensate. Condensing
boilers have large or two heat exchangers to take full advantage of
this reused heat. "A" rated condensing boilers reduce substantially on fuel use and carbon emissions.
It is now possible to control your condensing boiler and heating system through a smart phone or web interface.
We can install intelligent heating systems and guide you through using the service so you can further manage the reduction of your energy
consumption.
BENEFITS OF CONDENSING BOILERS
"Condensing technology is one of the cleanest and most
economical forms of heating, with the capture of additional heat
from the flue gas achieving gross efficiency levels of
98%." Viessmann
"Put simply with a non condensing boiler every £40 of a £100
bill is in wasted heat whereas with a condensing boiler only £10 of a
£100 bill is in wasted heat." Energy Savings Trust
By installing "..a new [condensing] boiler and a full set
of heating controls could save you between £190 - £230 and 1.7
tonnes of CO2 a year." - Energy Savings Trust
Underfloor Heating
WHAT IS UNDERFLOOR HEATING
Underfloor heating works by using a series of flexible pipes that
sit neatly under the floor and transmit heat by conduction and
radiant heat rather than convection. This warms the room more
uniformly and from the bottom up rather than by convection
currents produced by a radiator.
BENEFITS OF UNDERFLOOR HEATING
Radiators transmit heat through convection currents that
creates a swirl of dust within a room. Underfloor heating
produces heat through radiation cutting out dust so that the
air you breath is cleaner.
"Large spaces, which are difficult to heat evenly from perimeter heat
emitters, can be uniformly heated. They are unobtrusive - they do not
take up any space within the occupied area. ....The low return
temperatures will slightly raise the efficiency of all boilers, and
especially of condensing boilers" Energy Savings
Trust
" Underfloor heating can help reduce bills by around 5 per
cent." Energy Savings Trust
Unvented Cylinders
WHAT IS AN UNVENTED CYLINDER
Unvented cylinders provide hot water at mains pressure. This means
fast filling baths and powerful showers. Twin coil versions are
designed to integrate into solar hot water systems. The bottom coil
is connected to the solar hot water. The top coil connected to the
condensing boiler is used only when necessary.
BENEFITS OF UNVENTED CYLINDERS
Powerful showers and fast filling baths. Twin coiled versions are
environmentally friendly and efficient way of providing domestic hot
water.
Viessmann's range of unvented Vitocell cylinders provide excellent
heat energy savings with a heat loss of "...'1C during a 24
hour period"
