wolfe10 Report post Posted December 31, 2019 What electric furnace are you asking about? Share this post Link to post Share on other sites
manholt Report post Posted December 31, 2019 If it's a Attwood, it runs and heats on gas..only elect involved is to start burning gas. If it's a Aqua Hot, it will run on elect or diesel. Share this post Link to post Share on other sites
richard5933 Report post Posted December 31, 2019 I think that there's also an LP version of the Aqua Hot system. http://www.aquahot.com/Products/RV/400P.aspx Please provide more information (coach make/model as well as the furnace make/model) and it will be easier to give you some help.

richard5933 Report post Posted December 31, 2019 Isn't a Coleman Mach an a/c unit? Looks like they can be installed with a heat pump feature. What year is your Tiffin? I was looking at the manual for the 2015 model, and it looks like they came with heat pumps in the a/c units and an Aqua Hot unit. Not sure exactly what you have, but if it's like the 2015 then the system automatically turns on the Aqua Hot when the temperature inside is such that the heat pump won't be able to handle it on its own. Hopefully someone with a Tiffin will join in and give you more specific info. Share this post Link to post Share on other sites

A friend has a 2017 Entegria and is equipped with a propane Aqua Hot and he loves it. I contacted A/H and asked if there was a conversion kit from diesel to propane. ON DICE, you can change it our for a bit over $7,000.00 +. Maybe sometime way in the future. Herman Share this post Link to post Share on other sites
rayin Report post Posted December 31, 2019 Helps us out, is this a rooftop or basement Coleman-Mach? What is the year and model of your Tiffin? Without specifics, you will only receive general replies. Share this post Link to post Share on other sites

manholt Report post Posted January 1, 2020 Agree! Don't know if Tiffin ever had a basement AC. Several brands have both heat pump or heat strip on their roof top AC units...Never heard it being called a furnace before! Share this post Link to post Share on other sites
rayin Report post Posted January 1, 2020 I suspect this involves heat strips. There is an aftermarket electric furnace; Cheap Heat The installation manual contains more detailed information than the website. Share this post Link to post Share on other sites
