my boiler is hanging in between my 2 grow chambers connected by ~3m 8mm hose.
my bathroom is ~ 8m far away - i connected 2 x 8m garden hose (cold in - hot out) to the boiler
and taking a shower i have to carry both hoses to the shower - click&plug cold in to the cold water und push the hot water out of the boiler.
as the appartment is not mine i can`t do a fixed installation and still have the possibility to use the oil central water heating.
My aim next winter is to heat the whole appartment with my lamps and maybe build a grow chamber with lower vertical sections to grow letuche and herbs.
My ~calculation for 2 pers. in a 75m² appartment is as follow:
jan feb march april may june july aug sept oct nov dec
900 900 600 600 300 300 300 300 600 600 900 900W lamp
this is an average consume of ~ 9KWh / day // 3250KWh / year
i pay € 0,25 / KWh = € 812,50 total
2015 i had to pay € 1044,40 for hot water, heating + additional costs
2016 only € 647,33 because i started to prepare my own hot water.
300w lamp 12-15h = 80L of hot (40°C) water.
If you have a sunny place to fix some pv-panels you can do even better buisness.
Watercooled pv-panels produce 10-15% more electr. if in summer you cool them down
from 70° ---> 35°C. they are able to produce ~700W per hour of heat for the heatexchanger.
THink about global warm up - as we loose slowly our ice caps there will be less sunlight
reflected back to space. We just ignore that a reflective white (albedo effect) is the strongest weapon against climate change.
Plants are perfect for (water)cooling the world.
Unfortunately the deforestation of the planet is a fact - and many little greenhouses with solar panels in the cities only a dream - till now.
