Editorial Review :
The Mr. Heater MH35LP 35,000 Btu portable propane radiant heater is perfect for construction sites where you don't need to heat more than 800 square feet. The MH35LP is a radiant heater, which means it directly heats objects in front of it instead of the surrounding air. This makes it very efficient: you can get up to 12 hours of use from a 20-pound propane cylinder. Hook-up is simple using the included hose and regulator, and handy jobsite features include a folding handle, transport wheels, and convenient piezo push-button igniter. Rugged steel construction means that this heater is going to last, too. CSA Certified. One-year limited warranty.--Josh Dettweiler What's in the Box

Choosing a space heater is a matter of sifting through a bewildering array of types, power ratings, and fuel sources. Let's break it down a little to make the process easier. What are the different types of space heaters?
- Radiant heaters emit infrared radiation that directly warms the objects in front of the heaters (rather than the surrounding air). If you only need heat by a desk or in a small section of a room, a radiant heater is quiet and will use very little power.
- Forced-air heaters use a fan to blow air that has been warmed by metal or ceramic heating elements. A forced-air heater is appropriate for quickly heating up a small- to medium-sized room, but can be noisy.
- Convection heaters draw cold air from the floor; the air is warmed by heating coils and emitted from the top of the heater. A convection heater is appropriate for quickly heating up a small- to medium-sized room, but also can be noisy.
- Radiators work by heating oil enclosed in a reservoir, gradually heating the surrounding air. If heating speed isn't an issue, you might want to opt for a radiator. These are extremely quiet and effective--perfect for bedrooms.
Should I buy an electric or a combustion model?
If you want a heater that will be available in emergencies, or that can heat areas larger than a single room, choose a "combustion" model--one that is powered by a gas or fuel like propane, kerosene, natural gas, or diesel. Which fuel type you choose depends largely on convenience and local availability. For example, diesel would be appropriate for a heater you take with you on long car trips. How powerful a heater do I need?
Heaters are rated by BTU, which stands for British Thermal Unit (the amount of heat needed to heat one pound of water by 1 degree F). To find out how many BTU you need:
- Calculate the volume of the space to be heated by multiplying square footage by height.
- Multiply that number by 4 if your insulation is poor, 3 if it's average, or 2 if it's good.
The resulting number is a ballpark figure for how many BTU you'll need.Do space heaters cost a lot to operate?
As a general rule, electric space heaters are more expensive to use than combustion models. To ensure energy efficiency, a thermostat is a must-have feature for any heater. For radiant heaters, models with a 360 degree heating surface can heat larger spaces. If you need a forced-air heater, models with ceramic elements tend to be more efficient. Are space heaters a fire hazard?
Space heaters are implicated in about 25,000 residential fires every year. To ensure proper safety, always follow the manufacturer's usage instructions and fill out the warranty card to receive informational updates from the manufacturer. Also, look for extra safety features such as an automatic shutoff switch that can shut down the unit if, for example, it gets upended. In addition, choose a model where the heating element is adequately enclosed within the unit.

Propane Heater
This Mr. Heater is an excellent product, and I received excellent service from Amazon. It arrived exactly when they said it would, and it works like a charm. It's my second one, and I'd buy another through Amazon. Thanks again!

Return to sender?
I ordered a Mr Heater in December. I received the product no problem. I ordered another in January. When I received it was in a plain box and the main hose plus a screw was missing. We found a screw that would fit and I called Amazon to send the missing part. A very bored man told me to return the product and get a new one. I tried to explain I only needed a part but he did not want to do that. I was very dissatisfied with that response and I will not be buying anything from them in the future.
The product is wonderful if you can get it.

Finally, a heater that puts out enough heat ! ! !
I bought 3 other type of heaters with-in three weeks before trying this one. It works great. We use it to keep warm as we enter and exit our Hot Tub on our patio. It is easy to use and puts out more than enough heat, even on days when it was below 30 degrees. It would be nice if there were a way to regulate the heat output. On warmer days we just move the heater farther away and on colder days we move it closer. Very satisfied with this purchase.

Mr. Heater keeps work going.
Mr. Heater 35,000 BTU Propane Radiant Heater #MH35LP
This heater is just what I was looking for. Enough heat to keep work going out in the shop when the temperature drops below freezing without the kerosene smell of some other heaters. Easy starting.

Does the job
This is a powerful heater. We use it for fall and winter parties in our huge unheated garage. You would need a bigger model, or two to adequately heat a really big space in winter, but in the fall it is just right. Easy to use, seems quite efficient. Wish it wasn't so ugly!

Question : How safe is a wood burning stove/furnace
My husband wants to buy a wood burning stove to heat our home in the winter time because of the cost of propane. He will have it installed in the basement (concrete floors) and he said the radiant heat will flow upwards and heat the entire house. My fear is that our house has tongue and groove knotty pine throughout 75 % of the upstair's ceilings and walls. The knotty pine has been stripped and varnished with polyurathane from when the house was first purchased around 9 years ago. My fear is that the wood stove could catch the knotty pine on fire. He thinks I'm being silly, but I'm just trying to be cautious. What are the pros and cons of a wood burning stove for heat
Answer:
A husband who thinks his wife's fears are silly sleeps on the couch, rightr No, you aren't silly. The thing needs to be installed properly and, most importantly, the vent pipe must be done well especially where it goes through the wall and, once outside, it must clear roof lines or there is great danger that the products of flames will back up into the house (not good if that happens). Radiant heat only flows in a straight line and does not go through any material except air. So, you'll need to arrange to allow the heated air to flow up and (surprise, surprise) the cool air to flow down to be re-heated. Depending on the source of the wood, it will heat three or four times. Once when the tree is cut, once when it is sawn, and again when it is split. Much more convenient might be a stove that burns corn or wood pellets.

Question : How much should solar hot water and radiant heat cost in Maryland, USA
I'm getting quotes for a replacement for our hot water heater. So far I've gotten 22K for materials and installation of a solar hot water heater (3-4 collector panels) with heat rejection and single zone open direct radiant heating to one floor (accessible through drop ceiling underneath). Both quotes include a backup hot water heating system; the expensive one would involve installing a new backup high efficiency heater by converting our propane tank to use for heating. This would be either the Polaris or 2 Takagi Jrs, one for the solar hot water and another to power the radiant heat. Another quote is for 12K for only the solar hot water and heat rejection using the Velux system.Are these really high I've already contacted 3 companies but it doesn't look like too many people are installing them in Maryland yet. I'm still waiting on a quote from one final company. Thanks
Answer:
Without information of how big the footprint of the house is, and how many people the domestic hot water (DHW) is for, it is hard to say.You said you got a quote for 3 -4 collectors, so I'm going to make some assumptions based on that. Four 4'x8' collectors = 128 sq ft of collector. A general rule of thumb for space heating with solar is 1 sq ft of collector for every 5 -10 sq ft of house footprint (depends on heat storage, heat loss in the house, climate, etc). So, if we say 1200 sq ft house, 1200 / 10 = 120; 128 sq ft of collectors could work (again, depending on above variables). Depending on the brand, each flat plate collector could cost about $1000, so $4000 for the four collectors (evacuated tubes cost more). You then need a controller, storage tank, pumps, heat exchanger, plus all of the copper pipes and fixtures. Then a couple of days for a plumber to install. $12,000 installed seems about right without the backup heater. Here's a heating system that costs that just for the equipment http://www.altestore.com/store/Solar-Water-Heaters/Climate-freezes-Closed-Loop-Systems/Combined-Sola r-Hot-Water-Space-Heating/Heliodyne-Solar-Hot-Water-Space-Heat-1500-sqft/p6731/.Note, gas on-demand water heaters like the Bosch Aquastar make great backup heaters for solar http://www.houseneeds.com/shop/HeatingProducts/WaterHeating/AquaStar1/aquastar1600psmain.asp. I don't know what size you'd need.
