14:11:15 From Brian Gaulzetti (Dandelion Geothermal) : the enhanced air flow of heat pumps also helps with temperature consistency 14:17:29 From TK : Are you suggesting the mini-splits because fixing the ducts and sealing them is too expensive? 14:18:36 From Brian Gaulzetti (Dandelion Geothermal) : sometimes installing ductwork in an existing home is not practical since you would have to get to duct work behind walls or installed in ceilings and such 14:19:52 From Brian Gaulzetti (Dandelion Geothermal) : the split units don't use ductwork at all. 14:20:43 From Brian Gaulzetti (Dandelion Geothermal) : Trench from the borehole to your house is about 4' deep so that the pipe can stay below the frost line 14:23:05 From TK : But if we have ducts that aren't as well sealed, would your advice still be to go with the mini-splits? 14:23:42 From Brian Gaulzetti (Dandelion Geothermal) : We would assess the ductwork and potentially suggest ductwork improvements like Aeroseal 14:23:50 From Belinda Gingrich : Installing a central rather than a mini split can work if you have an unfinished attic/basement to install the duct work. If you already have functioning duct work it is probably best to go with a central system but it depends on the house configuration and if you want zones. 14:23:56 From Brian Gaulzetti (Dandelion Geothermal) : but no. If you have ductwork then a ground source heat pump will be great for you 14:24:15 From TK : Thank you. 14:24:45 From TK : Is it safe to assume that the water heater replacement is something that can be done regardless of which path one takes. 14:24:52 From Brian Gaulzetti (Dandelion Geothermal) : There are cost savings in the summer too with ground source heat pumps! 14:25:38 From Brian Gaulzetti (Dandelion Geothermal) : Yes! You can and should get an air source heat pump water heater no matter what type of heating/cooling system you have! 14:27:54 From Belinda Gingrich : With ground source you can have the water heater has part of they system. Heat pump hot water heaters do have some considerations. They need space and can make some noise. There are some other options as well depending on the location. 14:28:36 From Brian Gaulzetti (Dandelion Geothermal) : Very good point about timing Bob! 14:30:32 From TK : So if we are able to get a Ground-source heat pump we may not need a separate hot water heater? 14:31:52 From Belinda Gingrich : The GSHP will preheat the water. It will need an electric resistance heater to bring it up a little bit. 14:32:14 From Belinda Gingrich : That will all be part of the system. 14:33:29 From TK : Oil 🙁 14:35:39 From Belinda Gingrich : Will you be installing water to water in the near future? 14:36:25 From Belinda Gingrich : how much space do you need for your rig? 14:36:45 From DT : Is detailed temperature data for Lincoln availanble 14:36:49 From Belinda Gingrich : What brand heat pump do you install? Is it your own brand? 14:37:44 From PM : If we want to install ducts (assuming unfinished attic & basement) how much does that increase cost? 14:38:30 From TK : A few questions: 1. What are the conditions under which you wouldn't be able to help? 14:38:41 From TK : 2. Are there others in Lincoln who have switched over? 14:38:59 From JH : What's the typical lifespan of the geothermal unit in GSHPs? 14:39:00 From TK : 3. Does the price include removing the oil furnace? 14:39:39 From DT : Is detailed temperature data available? 14:40:46 From DT : How much time per year below 10F, 0F. 14:52:58 From TK : Thanks J., I thought I was missing something really obvious. 14:58:17 From RH : It looks like Dandelion prefers ducted systems to ductless. Is this true? If so, why? 15:00:36 From Brian Gaulzetti (Dandelion Geothermal) : bgaulzetti@dandelionenergy.com 15:00:46 From Brian Gaulzetti (Dandelion Geothermal) : 914-809-8932 15:01:53 From Brian Gaulzetti (Dandelion Geothermal) : Dandelion does not do water to water heat pumps. But we do have ductless geothermal units currently being installed in NY. We haven't expanded that product option to other territories yet, but likely will soon! 15:03:00 From Brian Gaulzetti (Dandelion Geothermal) : we install Enertech Heat pumps. They are a heat pump manufacturer based in South Dakota. and they double their standard warranty for all Dandelion installations. 15:04:05 From Brian Gaulzetti (Dandelion Geothermal) : Ductwork can be 10-25K per floor. Its a big variable based on how much ductwork is needed and how busy the ductwork installers are 15:05:24 From Brian Gaulzetti (Dandelion Geothermal) : we wouldn't be able to drill if the property is too wooded, hilly. And as of right now we only do installations in homes that have or can get ductwork 15:06:58 From Brian Gaulzetti (Dandelion Geothermal) : Ground source heat pumps are designed to last 25 years. The are incredibly efficient with no dirty hot fuel combustion. And there is no equipment exposed to outside weather (and rodents!). There is no required annual maintenance. 15:07:34 From Brian Gaulzetti (Dandelion Geothermal) : the price includes removing the furnace AND the outdoor air condenser unit. 15:08:01 From TK : What happens at the 25 year mark? Would a new set of holes need to be dug? Also, i am assuming the Enertech system could be replaced before the 25 year mark. 15:08:41 From Brian Gaulzetti (Dandelion Geothermal) : @DT The outdoor air temperatures do not matter since the ground source heat pumps don't interact with the outdoor air temps. The efficiencies stay the same all winter long 15:09:36 From Brian Gaulzetti (Dandelion Geothermal) : When you need a new heat pump after about 25 years, you just need a new heat pump. The ground loop can be reused over and over. 100+ years 15:13:24 From Brian Gaulzetti (Dandelion Geothermal) : thanks again everyone. Please give me an email- bgaulzetti@dandelionenergy.com
