I have three questions regarding electric heaters.
1 - Is there a difference between electric heater and radiant heater ?
when i think of electric heater, this is what i mean - >

2 - Are electric/radiant heaters quieter than fan-heaters ?
3 - Does electric/radiant heaters use more electricity than fan-heaters and air-conditioner ?
(if so, how much more do they use ? Would it be much more expensive or a little bit more expensive ?)
Thank you.
Answer
Short answer: nearly all "room size" plug-in electric heaters here in the US consume 1500 watts @ 110 volts. Built-in electric heat (such as baseboard or in-wall) as well as a electric central heat are 220 volt and more economical to operate (typically rated at 5000, 10000 or more watts).
Tedious detail: "radiant" heaters supposedly radiate their heat to warm objects in the room rather than heating the air . . . . . while a "convection" type heats the air in the room. Most convection types are fan forced (central hot-air heating is convection heat . . . . . central hot-water heating is radiant heat).
Radiant heat can be a steadier heat - while convection heat can be spotty (ie you feel warmer when it is running with a fan on/cooler when off) ........... but fan boosted heat can warm a room faster than a radiator.
A plug-in electric space heater can be either pure radiant heat (you're looking at the heating element which usually has a reflector behind it to "radiate" the heat in the right direction) . . . . .or it can be fan-boosted convection type . . . . . and most often a combination.
Old plug-in heaters of the 30s & 40s were usually 100% radiant and used metal heating coils, like a light bulb or stove burner. Many newer ones use quartz tubes instead of metal coils - that appears to be what is shown in both of your photos. Quartz tubes have an advantage of heating-up quickly - - so quickly that they can actually "pulse" on-and-off producing a uniform heat while using less electricity. The downside is that the quartz tubes burn-out and need replacing from time-to-time. The popular "Edenpure" type heaters are really quartz tube heaters enclosed in a cabinet - the quartz tubes in the Edenpure cycle on-and-off, but radiate their heat to a copper plate which releases it in a uniform flow.
If you have access to Consumer Reports or their Annual Buying Guide: CR periodically tests space heaters. They generally don't think that the "Edenpure" or "Amish Fireplace" style heaters are worth the expense. They eliminated some makes & models from consideration for safety reasons. We bought the "low profile" unit made by Honeywell that they've recommended for a couple years: it uses an electric strip heating element and can be used with-or-without the enclosed fan - the idea is to use the fan to quickly heat a cold room, then use without fan for a quiet, uniform heat. We're very satisfied.
You mentioned an air-conditioner - - - - a "heat pump" is just a reversible air-conditioner. Very convenient source of heat - if you are in a temperate climate, but not very efficient in a cold climate where winter temps stay below about 45 degrees F . . . . in fact, most heat-pump installations have electric resistance heat as a back-up.

tips and hints for conserving water and electricity in the home?
anonymoush
me and my dad are struggling to pay the bills at the moment, and wanted to know if anybody out there knows of any ways that we can cut back on our uses of electricity and water.
we turn lights off after we've been in a room. the majority of the time, we rely on natural day light, and at night time, we have a lamp in the living room which is bright enough to illuminate the whole room.
if we get cold. instead of putting the heating or fireplace on, we grab our dressing gowns, jumpers or blankets to keep us warm.
i hand wash the majority of my clothes (apart from difficult things, like bedding, jeans, jumpers and so on) and hang them up to dry.
we turn off and unplug all electrical appliances that aren't in use.
because it's just me and my dad, we don't make many dirty dishes in a day, so what ever we do use, we leave till the end of the day and wash them all together.
i've started to shower every other day (instead of every day) and use dry shampoo and baby wipes in-between showers to freshen up, and have managed to cut my shower time down to five minutes,
and i know this doesn't sound pleasant, but we have the "iff it's yellow, let it mellow" rule for our bathroom (which does get flushed and cleaned and attacked with bleach at the end of every night without fail!)
noting seems to be working to cut down the bills. please can anyone offer any help?
i forgot to add that i rarely use the hover, and sweep the house instead. take more time, but uses less electricity...
we don't have an AC cooling system, and we don't have sprinklers for the garden (our garden needs very low maintenance, luckily enough) and as for cooking food, we normally have microwaveable meals or just snack on crisps, biscuits and sandwiches (me and my dad aren't very big eaters)
thank you so much to everyone so far who has offered some help and suggestions :) xx
Answer
It sounds like you're already doing everything you can to conserve water and electricity.
One suggestion I would make is if you have an electric water heater, do your hot water tasks at one time, then go to your electrical service panel and manually trip the breaker for the water heater. The breaker is usually a 220 volt breaker (double height). Reset the breaker about an hour before you need hot water.
Another big energy user is the refrigerator. Get a thermometer and check the inside temperature of your refrigerator at the top (heat rises). If it is significantly lower than 40 degrees F, you can squeak the temperature control a little higher. Check the refrigerator temperature over the next 24 hours before making any further adjustments. This gives the temperature time to stabilize. The temperature must be below 40 F. If your freezer has an independent temperature control, set its temperature to about 28 degrees F.
In general, use any electric appliance with a motor (dishwashers, clothes washers, dehumidifiers, air conditioners, etc.) only when necessary. AC motors consume significant amounts of electrical energy.
Lighting usually accounts for only 10 to 15% of the average electric bill, but if you haven't already replaced your incandescent bulbs with fluorescent, do so. In the area of lighting, another cost saver is LED lamps. LEDs are even more energy efficient that CFLs (compact fluorescent lamps). The down side is that they are still quite expensive.
I honestly don't know what else to tell you. It sounds like you're already doing everything that can reasonably be done to save water and electricity.
