Hi All
I am a newbie here! I am a sparky by trade and have been rebuilding/extending/developing our property for 3 years! (living on site in mobile home!) The building has being totally refurbished and insulated above the latest building regulations. Upvc windows and doors have been installed throughout with A grade energy rating.
GROUND FLOOR
External walls 100mm concrete block/50mm cavity/50mm celotex /100mm concrete/dot and dab 12.5mm plasterboard
External walls old existing part of bungalow 100mm concrete block/50mm cavity/100mm concrete block/25mm cavity/tlx multifoil insulation/25mm cavity/12.5mm plasterboard
Internal walls 100mm concrete block.
Floor concrete slab/100mm Celotex 75mm of screed.
Under floor heating
1[SUP]st[/SUP] FLOOR
Attic truss construction with 22mm chipboard flooring & stud walls
Under floor heating
Roof
Barnstable concrete tiles
Over rafter TLX multifoil insulation
90mm of celtex internal/ vapour barrier/ plaster board.
Ventilation
A Nuaire MRXBOX95B-WHI mechanical ventilation system with heat recovery ( up to 95% efficient ) & summer bypass has been installed throughout the property
Solar Thermal kit (frame and pipe work already installed)
2 x ETZ5830 Barilla TZ58-1800 30 Tube Collector
1 x barilla deltasol c plus controller.
1 x Inter Panel Connection Kit with Expansion Compensator
1 x 24L High Temperature Expansion Tank inc. Connection Set
1 x Lead Roof Slates with Grommets (pair)
1 x PRV Discharge Container
1 x PRV discharge pipe
1x Drain Off Kit to suit DN16 Pipe
2 x 15m DN16 Pre-insulated Stainless Steel Flexible Pipe
1 x DN16 Connector Set (Type A)
1 x 10L Solaris PG Concentrated Heat Transfer Fluid
HEATING REQUIRMENTS
Wet Under floor heating has been installed with a separate manifold to supply each floor. The under floor pipe runs have been spaced at 150mm centres, separate zones and thermostats for each room.
5 x Towel rails have been installed on a separate circuit so that they can be run independently of the under floor heating system and used as a heat dump.
HOT WATER REQUIRMENTS
Ground floor
1 sink in kitchen
1 sink in utility room
1 sink in the wc
1 sink in the bathroom
1 combined bath/shower in the bathroom
1[SUP]st[/SUP] Floor
3 x bathroom sinks
3 x showers
1 x bath
overall heat loss has been calculated to be 8.9kwh
i have acquired a 16kw daikin altherma low temp ashp and am looking for any advice, suggestions, comments, regarding the best way to combine the different heat inputs and making the system as efficient as possible, my thinking is as follows;
1 x 450l three coils twin tank as per attached diagram
The diagram is not of my actual set up but the general idea is there. i intend to feed the upper buffer tank with the ashp at low temp and with the solar through the coil.
The the lower DHW tank will be heated by the ashp via a valve to divert the flow from the buffer to the dhw tank coil when the tank calls for heat this will be at the higher temp 50 deg.
Off of the buffer tank i will feed 2 underfloor heating manifolds which are controlled by there own room stats,zones,and pumps, also i was going to have the towel rail circuit coming from the buffer which again would have its own timer, pump and zone valve, this would also operate as a dump circuit should the solar get to that point.
The addition to this was utilising the wood burner that we are going to have any way. i thought that in the winter when we lite it we could could have a back boiler on it which could contribute to the hot water i was thinking this would feed a vented tank then the cold water would go through the coil pre heating it before it enters the dhw tank.
my plumber mate has suggested the gledhill torrent, I am not sure if it would be the most efficient solution due to the fact the whole tank would need to be heated to the higher temperature from the heat pump and would it cope with the hot water demand?
any comments, advice, suggestions would be greatly appreciated
