BikBok Posted December 27, 2009 Report Share Posted December 27, 2009 Our new place has an HRV system (heat recovery ventilation) which will be new to us. Do these affect the tanks much? Those of you with an HRV system, can you tell me what sort of maintenance is needed on them and do filters need replacing etc? The system if it's as old as the house would be about 4 years old. We're moving in next month. Quote Link to comment Share on other sites More sharing options...
Floater Posted December 27, 2009 Report Share Posted December 27, 2009 Have had HRV in our place over 2 years, dont touch a fing. No difference on tanks, tanks have lids anyways. What Mystic said, I've been living in my place with an HRV system for 4 months and haven't done anything. If anything it will make it so your tank heaters don't have to work so hard on cooler days as the heat that accumulates in your roof helps to heat your house to the temperature you set.

BikBok Posted December 27, 2009 Author Report Share Posted December 27, 2009 thanks. I'm looking forward to a drier home and maybe even an improvement in my allergys. Quote Link to comment Share on other sites More sharing options...
WEKA Posted December 28, 2009 Report Share Posted December 28, 2009 Best investment I have made. Had dehumidifier running 24hrs to keep water off window sills. Not even a mist now from day it was installed. Mine has indicator on panel to tell when filter needs replacement. Have not required new filters yet, only a few months old. Strongly recommended.

David R Posted December 28, 2009 Report Share Posted December 28, 2009 Doesnt help if its cold outside, cold inside and cold in yur roof-space. Its still cold, lol. Exactly, when the roof space is at its hottest you won't want hot air circulated through your house, and vice versa, so you lose all the advantages of having clean air circulated. Heatpump FTW. As for maintenance, is it actually an HRV brand? I'd just check their website. Quote Link to comment Share on other sites More sharing options...
BikBok Posted December 28, 2009 Author Report Share Posted December 28, 2009 we're told it's a HRV but we'll check when we move in. It is what it is and it's not a heatpump so just need to work with the existing setup. Heating is gas. Quote Link to comment Share on other sites More sharing options...
Scottie841 Posted December 28, 2009 Report Share Posted December 28, 2009 They are very good at keeping the house a constant temp and they do drop the humidity (because the air in the roof is dryer) As for looking after it you will need to change the filter on them every year. This is easy to do. All you do is take the big sock (looks like filter wool) off and put a new one on. Quote Link to comment Share on other sites More sharing options...

Scottie841 Posted December 28, 2009 Report Share Posted December 28, 2009 I am not sure of the price but you get them from anyone that sells the HRV system. I know the ones for DVS are cheap so would guess that HRV would be under $20 but am not sure of the exact price Quote Link to comment Share on other sites More sharing options...
HelenMac Posted December 29, 2009 Report Share Posted December 29, 2009 hrv filters need replacing every two years, price is dependent on how big the system is. Just make sure you find out when the last filter change was. HRV normally send a reminder when its due. Quote Link to comment Share on other sites More sharing options...
jim r Posted December 29, 2009 Report Share Posted December 29, 2009 As above and the cost of changing filter is around $300. Quote Link to comment Share on other sites More sharing options...

darkfur Posted December 31, 2009 Report Share Posted December 31, 2009 I find the DVS we have fine but our heat pump you can't keep a tank near as it evaporates it really quick, even with a lid on Quote Link to comment Share on other sites More sharing options...
WEKA Posted January 1, 2010 Report Share Posted January 1, 2010 The heat pump should not cause evaporation unless you are in cooling mode!!!!!! The HRV will be more likely to be the cause as it really does dry out the house. Maybe the air absorbs more moisture when you are heating.

Lower relative humidity=more evaporation. Quote Link to comment Share on other sites More sharing options...
