I am currently working on a rehab and have no HVAC. I am currently using a kerosine space heater, but they are not safe for indoor use.

Does anyone have a suggestion on a good heater to use while doing a rehab house?

HD has a HearthSense30,000 BTU, Ventless Dual Fuel Blue Flame Heater With Base and Blower, T-Stat Control

Model# 140324 .

Has anyone used one of these and do they work well?

Thank you for your time.

Thank you Plenty. I will need to look at lowes as well

Has anyone used one of these?

Comfort Zone1500-Watt Electric Milkhouse Utility Heater

Model# CZ799BK

We use the box-type radiant heaters: boxes on wheels, lightweight, efficient. Like this:

I keep oil-filled space heaters for such purposes. We ran one for years on a timer to keep our kids' pet bunnies warm in an unheated porch ( spoiled bunnies, but so cute! And sweet!) Never had a concern about overheating, even though there was dust, fur, and hay around.

I bought extra outlet timers that I could pull the set pins out to use them all on one timer. Thus, i could have the heater on for, say, two hours, off for an hour, and on again throughout the night. But, I suspect someone makes an oil-filled space heater with a thermostat. Using that same set up of on for awhile/ off for a bit/ on again, I did heat a rehab house for awhile through winter. Two months of $300 electric bills, and I decided to get the furnace done sooner, rather than later. That was on a 700 something square foot 2/1 with basement, several years ago. With current utility rates, I'd expect much higher electric bills.

I have a couple of the cheap milkhouse heaters I use in my garage and at remodels when I don't have heat. I leave one running constantly and it was keeping a 950 sqft house about 50 degrees when it was in the 20's outside. I plug the 2nd one in when I get there in the morning and have an infrared propane tank heater that hangs on top of a 5 gallon propane tank that I fire up and it will warm it up nicely in about 30 minutes.

Thank you everyone for the responses.

RB, I tried Googling that model, but nothing showed up. Is the one you are referring to electric?

A nice big gas grill with tank. (with the 2 side burners. (get extra tank) dual purpose. you can write it off as a business expense and when your done bring it home.

There's great sales going on right now.

Here is an update for the milkhouse heater that I am trying.

The upstairs to my shop is approximately 256 sq ft as it is 16x16. It is 29 degrees outside. The temperature in the building was 39 degrees and one hour later, after turning on the new heater, it was 52 degrees. So, the temperature rose 13 degrees in one hour. It is very similar to my older heater and thus I will buy a few more of these and place them throughout my project house.

ALL 1500 watt electric heaters put out the same amount of heat. Some like oil filled radiators take a little longer to reach temp but also longer to cool down,..but still the same BTU's

I wouldn't ever have a non vented heater, no matter propane, Nat gas, oil, kerosene etc.

Don,

I didn't read all the responses, but electric heat is VERY expensive. I think some sort of gas salamander would be good, but you can't safely run it when you're not there...it's more to warm the place up when you're working there. Do you need to worry about water freezing? If so, maybe get just a few electric space heaters just to keep enough heat going to prevent freezing, and use the salamander when you need to work there. IMO if you keep the interior temp around 40-45F or higher you won't have any freezing issues unless you have a water pipe on an exterior wall.

Try to use some other common sense tips also, such as on sunny days leave blinds/drapes open, buy some 3 mil plastic sheeting and temporarily put over windows, go ahead and insulate the attic better, and so on.

Blown insulation will help where spray foam more expensive is a completely air tight system that prevents any air infiltration. Avoid fiberglass as develops air pockets. Roxul batt where if have a 6" stud then will get a good R factor. If use cellulose then can get R 50 in the ceiling. Tenants will always want a rental home that has low utilities where they should pay a higher rent. A well insulated building then the HVAC system can be downsized where even without heat then the building will never go below freezing.
