1 - Description
PS ES+ Thermal Stores are intended for storing and subsequent distribution of thermal energy from solid-fuel fired
boilers, heat pumps, electric boilers etc. 230V or 3x230V/400V heating elements of 2-8.2 (12) kW output can be installed
directly into the 6/4” tappings. Tanks are fitted with three side tappings, one top tapping and one tapping for sensor
sheath. A 100mm thick insulation for these tanks is a separate item.
1.1 - Models
Three models of 560, 860 and 1037 l capacity.
1.2 - Tank protection
The inner surface has no finish, no anticorrosion protection, the outer surface is lacquered in gray.
1.3 - Thermal insulation
Tank insulation is available as a separate item, installed on the tank on the spot for easier handling. The insulation is
made of 100 mm thick fleece and fitted with a zippered PVC surface layer.
1.4 - Connection points on the tank
3 side tappings, G 6/4“ F thread
1 top tapping, G 6/4“ F thread
1 side tapping for sensor sheath, G 1/2“ F thread
1.5 - Packaging
The tanks are delivered standing, each screwed to its pallet.

4 - Operation
In a thermal store, heating water can be heated up by several heat sources like various types of hot-water boilers,
renewable energy sources or electric heating elements.
The thermal store shall be connected to a heat source through G 6/4” threaded fittings. Connections depend on the
circuits to be connected.
5 - Installation and Commissioning
Installation must meet valid rules and may be done only by qualified staff.
Defects caused by improper installation, use or handling are not covered by warranty.
After the tank is installed and connected to an existing heating system, it is recommended to clean the entire heating
system using a suitable cleaning agent, e.g. MR-501/R or a similar one offered by Regulus.
Anti-corrosion protective liquid for heating circuits should be also used, e.g. MR-501/F.
5.1 - Connection to heat sources
Place the tank on the floor, as close to your heat source as possible. Fit the insulation, cf. Installing Insulation on the
Tank. Connect the heating circuits to inlets and outlets respecting the thermal stratification in the tank. Install a drain
valve at the lowest point of the tank. Install an air vent valve at the highest point of the system. Insulate all the conne-
cting piping.
5.2 - El. heating element installation
The G 6/4“ side tapping is designed to accommodate an electric heating rod. A thermal store can be fitted with an el.
heating rod depending on the tank diameter and rod length. It can be controlled either directly (thermostat-equipped
elements), or by a heating system controller.
Warning: Electric heating elements shall be protected by a safety thermostat.
The installation may be done by qualified staff only.
5.3 - Commissioning
This tank is not designed for DHW heating.
The tank shall be filled up together with the heating system, respecting valid standards and rules. In order to minimize
corrosion, special additives for heating systems should be used. The quality of heating water depends on the quality of
filling water at commissioning, on the top-up water and on the frequency of topping up. This has a strong influence on
the lifetime of heating systems. Poor quality of heating water may cause problems like corrosion or incrustation, esp.
on heat transfer surfaces.
Fill the heating circuits with the appropriate fluids and air-bleed the entire system. Check all connections for leaks and
verify the system pressure. Set the heating controller in compliance with the documentation and manufacturer’s reco-
mmendations. Check regularly proper function of all control and adjustment elements.

6 - Installing Insulation on the Tank
Product description
Fleece insulation with PU leather surface, zippered.
Warning
Insulation installation shall be done in two or three persons, depending on its size. The zippered, PU leather surface
coated fleece insulation must not be installed at temperatures below 20 °C. If this cannot be avoided, the insulation
shall be pre-warmed in another room to at least 20 °C. It is impossible to install insulation of lower temperature, there is
a risk of damage, esp. to the zipper.
Do not use any tools for installation.
Keep away from open fire.
Installing insulation
1. Put the bottom insulation under the tank and place the tank following installation instructions.
2. Wrap the insulation around the tank carefully. Check that the insulation adheres to its body perfectly. This can be
reached by rubbing and patting the insulation by hand from its centre evenly in both directions until the insulation
adheres to the tank’s surface completely and no bubbles are left.
3. Use the holes for tappings as a rest during the insulation installation.
4. At least one person presses the insulation to the tank, pulling both ends together. The other person closes the zipper.
5. Put on the upper insulation and cover.
6. Push on the covering plastic rosettes depending on the size of tappings, or put on the flange plug(s) with insulation.
7. Finish the tank installation in compliance with the respective instructions and valid standards and rules.
Warranty on insulation
The insulation is covered by a 24-month warranty. This period starts the next day after the insulation is sold.
□ Warranty shall become null and void if:
○ the procedure described in the Installation Manual was not respected,
○ the product was used for other purposes than intended.
□ Warranty does not cover:
○ usual wear and tear,
○ damage caused by fire, water, electricity or another natural disaster,
○ defects caused by failure to use the product in compliance with its intended purpose, by improper use and
insufficient maintenance,
○ defects caused by mechanical damage to the product,
○ defects caused by tampering or incompetent repair.

7 - Maintenance
If the tank is fitted with a heating element, disconnect it from the mains first. Clean the exterior of the tank with a soft
cloth and a mild detergent. Never use abrasive cleaners or solvents.
Check all tank connections for leaks.
8 - Disposal
Packaging shall be disposed of in compliance with the valid rules. When the product reaches the end of its life, it shall
not be disposed of as household waste. It shall be dropped off at a Local Waste Recycling Centre. Insulation shall be
recycled as plastic and the steel vessel as scrap iron.
9 - Warranty
This product is covered by warranty according to the conditions described in this Manual and according to the Warran-
ty Certificate. A Warranty Certificate is an integral part of the supply.
