Short summary of my situation:
- Reconstructing a fairly old house in the Czech Republic in the countryside
- Adding insulation, 'relatively' airtight envelope (it won't be a country cottage anymore), so need mechanical ventilation
- I have the original plans and the recon has progressed to a point where I can now add the digressions and be confident things aren't going to change much/if at all.
- I have an estimate of the thermal load / energy losses for the rooms.
- The main room will have a wood burner with external air-supply.
- There will be a secondary heat source as a condensing gas burner that can supply hot water
- I want HRV installed with integrated air heater. I have the specs for the unit, which is selected. The unit has an additional air-recirculation circuit that has a high-volume flow mixing heated air with the fresh recuperated intake. It takes heat from the gas burner's hot water via internal exchanger.
- I can supply any info on local norms. I can supply specs for local duct catalog items. The norms can be bent here too, it's not like things have to be done bang on.
- I can supply info on local climate.
-This phase of the home is that it is a 1.5 floor (attic living space) rectangular 13metres x 9 metres home. Not huge. Oh yeah...all data metric (metres, kilowatts etc)
- Even though new regs are coming in making HRV mandatory for many residential homes in the next couple of years, there are practically no skills where I live in HVAC. I cannot find anyone I can trust. Even the main online retailer of these systems basically told me they don't have the know-how or capacity to do HRV+heating installation at the moment. It's a problem for me now. (I don't know if this could lead to further business for a remote contractor in the region, but if someone's interested in branching out I could help.)
What I need is someone to design the ducting based on local catalog elements and the local HRV/heater unit, and offer tips on installation which I would do or organize myself. All I need is a design on what to install where and how, with reasonable confidence in the ability of the final system to provide the comfort/heat needed, warnings on what to avoid, maybe with suggestions for one or two extra reserve elements in case it works out too cold in the winter. As an English expat living here in the CZ, no problems communicating in English by email/phone/Skype clearing up details, having a convo on the design, clarifying and supplying materials in English (though some will be in Czech I can point out the meanings of the terms)
Please could someone get back to me with willingness and approximate pricing and time frame for such design work?
Thanks in advance,
Frank
