Symbol for a necessary taskecoTEC combination boiler The ecoTEC combination boiler is a fully automatic, wall mounted, room sealed condensing (high efficiency) boiler for central heating and domestic hot water.
Domestic hot water is supplied directly from the boiler, without requiring a copper cylinder, cold water tank, feed and expansion vessel and associated pipework. Domestic hot water has priority over central heating. The ecoTEC plus combination boiler consists of 3 models with outputs of 23 kW, 31 kW and 37 kW for domestic hot water and two pro versions with outputs of 24 kW and 28 kW for domestic hot water. All versions are available in natural gas. The ecoTEC plus 831 is also available in LPG. EcoTEC combination boilers incorporate a warm start facility that keeps the domestic hot water heat exchanger hot, providing an instantaneous delivery of domestic hot water.
The temperature in the domestic hot water heat exchanger is limited by the boiler control system and it is not necessary to install a scale reducer on the cold mains to the boiler. However, in areas that get exceptionally hard water, a scale reducer may be fitted to prevent scale formation in the hot water system pipes. The heating system on ecoTEC plus combination boilers can be filled using the builtin filling loop contained within the boiler. EcoTEC system boiler The ecoTEC system boiler is a fully automatic, wall mounted, room sealed condensing (high efficiency) boiler for central heating and domestic hot water (where a separate indirect hot water storage cylinder is also incorporated in the system). The ecoTEC system boiler consists of models with outputs of 12, 15, 18, 24, 30 and 37 kW. All ecoTEC system boilers are available in Natural Gas. The ecoTEC plus 618 and 630 are also available in LPG.
1.3 General Notes The boilers have been designed for use with a sealed central heating system, and come fully tested and assembled with a built in circulating pump, expansion vessel and diverter valve (ecoTEC combination boilers). The boilers are easily mounted on any internal wall and can be installed with either a horizontal or vertical RSF (room sealed fan assisted) flue. The boilers use a standard flue system (100 mm or 125 mm outside diameter).
Flue extensions and additional bends and elbows are available for the flue system to4Instructions for installation and servicing ecoTEC / 83959209Introduction 1increase the flexibility. If desired, an inhibitor may be used in the system. Guidance on the use of inhibitors is contained in these instructions. All boilers have a built in diagnostic system which indicates the operational status of the boiler. This feature provides key information to aid commissioning and fault finding.
The data badge is fitted to the underside of the boiler. See text of General Requirements for installation requirements or notes. The Valliant ecoTEC are state-of-the-art appliances which have been constructed in accordance with recognised safety regulations.
Nevertheless, danger to the life and limb of the user or third parties can still occur or the appliance or other material assets be damaged in the event of improper use. The appliance is designed to generate heat for connecting to hot water central heating systems and for instantaneous hot water supply (ecoTEC combination boilers only). Any other use or extended use is considered to be use other than intended. The manufacturer/supplier is not liable for any resulting damage. Intended use includes the observance of the operating and installation manual and the adherence to the inspection and maintenance conditions. Any incorrect use is forbidden.
The appliances must be installed by a competent person, who is responsible for adhering to the existing regulations, rules and guidelines. 1.4 CE marking The CE marking shows that the appliances comply with the basic requirements of the following directives: - Gas appliances directive (90/396/EEC) - Electromagnetic compatibility directive with threshold class B (89/336/EEC) - Low voltage directive (73/23/EEC) The appliances satisfy the basic requirements of the efficiency directive (92/42/EEC) as condensing appliance.

Hive is basically a cloud connected thermostat with scheduling that lets you control your Heating or Heating and Hot Water from you phone or a computer. This post shows how to wire it up to your Vaillant ecoTEC plus 824. WARNING: this is information is to be used as is. I can also not guarantee it will work for you nor can I be held responsible/liable if you use this information.
NOTE: It definitely worked for me though. Vaillant ecoTEC plus 824 connections: The diagram below was taken from the Vaillant ecoTEC plus 824 manual, by default connections 3 and 4 are connected.
You will then need to work with the L, N, 3 and 4 pins to hook your combi boiler up. This loop above needs to be removed in order to install your Hive. Hive connections: Hive comes in two flavours, Single channel (Combination Boiler) or Dual channel (Combination Boiler or Boiler & Tank) Wiring your Hive into your Vaillant ecoTEC plus 824: Single Channel Receiver Wiring: Dual Channel Receiver Wiring: Using you Hive: After setting up the Network Link and the Thermostat (instructions come with the hive), you can then login on-line and create a schedule with set temperatures: It also logs the temperature for review: This entry was posted in. Post navigation. Hi thanks for this info, I have an Vaillant ecoTec Plus 835 and initially use the above post. It wouldnt power on so i think the “Blank” terminal to the left of the RT is No-Function. Gave a good friend a call and he suggested to not use 230v RT but to use the 24v option instead.
So my install was. (WARNING. just to cover my a$$, i offer this as advice and if you are unsure, get it installed by someone who knows) 5 core cable from the boiler to the Hive controller. Connected Blue to N, Brown to L, Green/Yellow to Earth, Grey to 1, Black to 3 to the Hive. Inside the boiler I connected Brown to L, Blue to N, Green/Yellow to Earth, Grey to 24v RT port 1 and Black to 24v RT port 2 i have pics i need to upload later. Erm.I have to disagree, using the 24v to control is not going to damage mainboard as the switching pings are rated at 240v and all’s I’m doing using passing 24v instead. 240v power pin 1 and 2 DO NOT interact with 3,4 or 5 and the as long as 24v switching go’s to 24v there’s no issue, If I put 240v to 24v, then yes there would be issues.
My good friend is a qualified electrician and his explanation made sense and the boilers been working happily so far, spent some time in loft (boilers in loft) insulating pipes and Ive not smelt and seen anything. Great thread, so useful, thank you, I also have a Baxi Duotec combi boiler like Will. The manual, and your diagram suggest that the permanent live and permanent neutral must be taken from the fused spur. Could I take those feeds from the L and N terminals in the boiler which connect directly to the fused spur, as this would allow me to do all the wiring from the boiler terminal block using one piece of 5 core cable. Otherwise I would need a separate cable to the fused spur, which is doable but messier and more faff and hassle. Here’s hoping this thread isxstillnlive and that you may be able to answer my query!
Hi Salti, I hope you can help me as really confused on whether my boiler is compatible with the Hive system or not. I purchased 2 Hive v1 units and are both still boxed. One is for heating and one for heating and hot water. The boiler I have is Vaillant Aquaplus which has a built in hot water store which is what confused me as to which unit I will need. I was planning to updgrade to the hive2 if hive1 worked.
Researched on the net but cannot find any info if anyone has installed the Hive on this particular boiler. I rang Vaillant and this woman in ‘support’ told me that my boiler doesnt have an ebus system so Hive or their vSmart wont work but not sure if I was told the correct info as I had opened the panel behind main controls and seen the live/neutral and also the loop on pins 3 and 4.
Would you please be able to advise if possibly Hive would work and which Hive I would need? Also if I did try to connect it as per L, N and 3 & 4 would it cause probs to my boiler if turns out to be incompatable? Thanks in advance. Hello and so sorry for the such long delay in my update. One thing after another, other probs in house and totaly forgot to post an update and say many thanks for the help and advice.
I managed to wire in the hive (took a while) and all working perfect thank you. I used the one with hot water too but should have only installed heating only. It still works so all good. It was quite difficult to wire in the connections to existing live and neutrals in the boiler and really need to use small connectors to extend wires and reconnect but it took so long that have left it as is as is working fine at the moment. Many, many thanks and very much appreciated once again as without your help I probably wouldnt have attempted to install it. Jon, the timer takes priority over the thermostat. The hive has a web interface for adjusting timings so i have moved to using this directly over the inbuilt timer on the 824 boiler.
The setup is: 1) Set the boiler timer up for 24hr heating schedule allowing the boiler to be on at any point of the day. Note: heating and hot water can be set on different schedules.
2) The hive is then setup as the thermostat to turn the bolier on/off. 3) The schedule for boiler on/off times is then setup through the hive web interface. Hi all, I purchased a Hive kit with the dual receiver as my current house has a combi installed, but I will soon be moving to a house with a conventional boiler and tank. I was hoping to use it on my current boiler before transferring it to my new house. The instructions and majority of reviews suggest that a single is required for a combi, but Salti’s original post suggests the dual can be used for both. Is this the case?
Do I just treat the Hot Water Off as the common when connecting to the combi? Thanks in advance. Installed the Hive on a new Vaillant Ecotec plus 825 Combi.
I had no other heating controls for the boiler For others people trying to do a similar job, I did exactly as this post and it is fully working. The L/N/E from the fused spur will be at the X1 terminal. Wiring instructions. I used a 5 core cable bought from Screwfix — Hive Receiver to Boiler at X1 L to L (brown) N to N (blue) 1 to L (black) 3 to RT 230v (grey) E thether to E (green/yellow) Took a while to get 3 wires in to the Live connection at x1, so take your time on it.
Remove the looped wire at the RT 24V (x100) Also a similar thread on this post then just follow the steps to connect the thermostat and internet controls Reply. Hi, I am looking to connect a Vaillant 835 to Hive.
Looking at all posts it looks like the Live on the boiler side would have 3 wires coming in. So I was thinking to get L, N and hearth of the hive from the same fused spur where the boiler is attached. Then I would need 1 wire to connect 3 in hive to RT in boiler. Finally 1 and L in hive could just be looped. This way I would use only 1 wire going in to the boiler and will leave the preexisting connections alone. Any thoughts much appreciated.
Hi Salti, Thank you for you succinct instructions. This showed me exactly what I needed to know in order to wire up my Hive receive to my Vaillant EcotecPlus 837.
Having mistakenly bought a Hive system that didn’t include installation (found in a John Lewis Christmas sales bin), I began to think that I was really up the creak. I couldn’t find a engineer willing to install it. So getting the system working was particularly satisfying.
The only drama I had was that I found that the heating would not come on with the timeswitch 130 still installed. Now I have removed that, what I need next is a replacement blanking plate.
