Where are ASCOT heaters manufactured? 

The Premspec Group Ltd has an ongoing, trusted relationship with a factory in Spain. ASCOT products are manufactured with the highest quality European materials. 


Can I return my ASCOT product? 


Returns are only accepted if there is a prior written agreement between customer and member of Premspec Group.

Premspec Group generally only accept returns of faulty goods, of which we would arrange collection from the address of the customer. The returns form must be requested and returned before this process begins. 

We do not offer a collection service direct from the site.

If you would like to return a product that isn’t faulty, Premspec Group issue a handling charge of 50% of the original cost price. Return must be arranged by the customer. 

If you would like to discuss the return of an ASCOT product in further detail, please feel free to call the office on 02921 303 710. 


What are the product’s guarantees? 


On our ASCOT thermo-fluid range, we offer 2 years on the electrics and 10 years on the material. 

For ASCOT dry panel heaters, we offer 2 years on the electrics and 5 years on the material. 

We do not offer an on-site warranty for our ASCOT products. 


How easily can I install my ASCOT product? 

All ASCOT products are very straight forward to install, all products come with an installation guide and can be plugged into a 13A socket or hard wired through a spur, which must be carried out by a qualified electrician. 

We begin by sizing up your room and recommending the correct heater for your installation, just get in contact and we can do this. 

Once installed onto the wall, you will then be required to set up the programming of your ASCOT heater. This is all displayed within the installation guide, however, we have simplified this through ASCOT how-to videos which can be found below:


How do I know which ASCOT heater to install? 


ASCOT heaters work at their most efficient when they are specified accurately.

We have an in house team who work with bespoke software to calculate the required number of elements for each space.

Our team will also advise on which type of heat is best suited to the dwelling/space that you are installing ASCOT heaters into. 

The following factors are considered in order to achieve absolute maximum energy efficiency and most importantly, comfort.

· Climatic period and zone

· Rooms and area in m2

· The type of dwelling

· Other factors that can contribute to heat loss and exposure to the outside elements 

Our technical studies are free of charge and we request that one is completed before you install any ASCOT products.

How does ASCOT heating rate on an EPC? 


Lot20 heating faces many challenges when confronted by an EPC assessor. Please see below link that will tell you everything you need to know.

ECOdesign LOT20 VS EPC


Are ASCOT heaters low surface temperature? 


ASCOT thermo-fluid radiators have the capability to become low surface temperature radiators, on request. Note low surface temperature setting can only be applied to ASCOT digital (non-Wi-Fi) thermo-fluid radiators. 

Shall you wish for a pre-installed ASCOT heater to become low surface temperature, please get in contact with our main office on 02921 303 710 and they will walk you through the correct procedures. 

If you are installing ASCOT heaters on your next job and wish for them to be low surface temperature, then we have an in house team that will configure this for you. 

Note: We request that an ASCOT technical study is completed before any heaters are sent out with the requirement for low surface temperature. A low surface temperature setting will have an effect on the power output of your heater, so a bespoke heating scheme is most certainly a requirement.


What is LOT20?

Lot20 is the new EU legislation as of January 2018 designed to remove inefficient products and technologies from the market.

Part of the ECODESIGN Directive, Lot20 concerns local space heaters, including those with solid fuel. It states all local space heaters that consume energy (electricity, gas or liquid) with a nominal heat output equal to or greater than 250W, must comply with a minimum energy efficiency standard, which ASCOT electric heating products achieve and even exceeds.

In relation to ASCOT fluid heating, the incorporation of smart technology such as open window sensors, 24/7 programmable timer, built-in thermostat and Wi-Fi technology make for a significant improvement on the outdated storage heaters that many associates with electric heating. 


Shall I install ASCOT thermo-fluid heating or ASCOT dry panel heating?

How do different types of heating work? 

The main difference is in the way they emit heat. 

ASCOT Oil filled radiators have an element which heats fluid inside. This is a thermal oil and transfers heat energy. This, in turn, warms the surface of the radiator, resulting in radiant infrared heat that is transmitted to the objects resulting in the room heating up.

ASCOT dry panel heaters have an internal element that produces hot air, which rises and is then convects around the room. 

Which is the most efficient?

ASCOT thermo-fluid radiators heat the oil inside the elements, and as the oil is inertia, the heat will remain within the fluids. This means that a) the radiator will not require to draw as much power to maintain comfortable room temperature, and b) the radiator will take longer to cool down after, therefore still radiating heat whilst no power is being drawn. 

ASCOT dry panel heaters produce hot air at a rate that doesn’t change respective to the room temperature. They also lose heat quickly once power has been cut. These heaters do, however, heat a space far quicker than oil-filled radiators, and turn off instantly when required.

Which one shall I use/install? 

This is, of course, totally up to you. However, we do have some recommendations. 

Within dwellings that require heating throughout the course of the day, such as living areas and office spaces, we would recommend an ASCOT thermo-fluid radiator. The performance of the radiator is far better for this type of requirement. 

Shall your space require instant heat, such as an unoccupied bedroom, a porch area, or a commercial area that is only occupied an hour or two a day, we would advise that you edge towards an ASCOT dry panel heater. A dry panel heater will be more efficient using this way as you are able to get the heat as and when you require, instantly.


Why should I choose ASCOT electric heating over gas? 

There are so many benefits to using modern Lot20 electric heating over a gas system. See link below for all information:


How can I make the most out of my ASCOT electric heater?

Premspec has provided ASCOT heating to the UK market to provide comfortable and low-cost heating in homes and commercial properties. In order to maximise your ASCOT heater is the most efficient way possible, follow the best practice guidelines below:

We always recommend that whilst using comfort mode, the temperature is set at 21°C to prevent excessive consumption but maintaining a comfortable living or working temperature. 

We advise that you do not cover ASCOT heaters, as this will have an effect on how the heat is emitted through space. This means that your radiator may then unnecessarily draw more power than is needed, having an effect on the efficiency and cost. 

Find a correct programming structure that works for you without being excessive. We recommend that comfort mode is set in a couple of 4-hour timeslots per day, whilst the anti-frost/eco mode is set during the other hours. This will ensure that space does not become uncomfortably cold without the radiator drawing too much power. 


How do I become a registered ASCOT installer? 

You will have to complete an ASCOT training course which covers Lot20 legislation along with the detailed education on ASCOT products.

There are currently 5 modules to the course, with a requirement of 3 modules to your name to become certified. You will take away a best practice installer guide of ASCOT products and your certification will go live on our website along with the rating of your certification. 

Simply just get in touch with the office on how you can register to come on one of our courses. 


What is Geolocation on ASCOT Wi-Fi heaters?

Geolocation feature essentially means that you can control your ASCOT Wi-Fi heater remotely, via the app. An example would be whilst you are at work, you can control your heater to ensure there is a comfortable temperature for when you arrive home. You can also use this feature to care for close relatives, such as the elderly, who may have restricted movement within their own home or a lack of knowledge on how to control their ASCOT heater. 


Can ASCOT heaters connect to central thermostats? What else can they connect to?

ASCOT Wi-Fi heaters do have the capability to connect to Nest central thermostat system. They are also able to connect to ALEXA.
